Abstract :

K0.5Na0.5NbO3 (KNN)-based bulk ceramics show superior piezoelectric coefficient by constructing the morphotropic phase boundary (MPB) between rhombohedral and tetragonal phases. However, it is a challenge for KNN films to obtain the superior electrical properties with the same MPB composition, because of the serious volatilization of alkali ions and substrate-induced stress. Therefore, the MPB composition in films could be different from bulk ceramics. The lead-free piezoelectric 0.92KNN-0.07BaZrO3 (BZ)-0.01Bi0.5Na0.5TiO3 (BNT) and 0.91KNN-0.08BZ-0.01BNT films were prepared, referring to the MPB composition of bulk ceramics. For comparison, the 0.95KNN-0.04BZ-0.01BNT and 0.88KNN-0.11BZ-0.01BNT films far away from the MPB composition of bulk ceramics were prepared together. Their crystallographic phase, domain morphologies and ferroelectric switching show a dependence of BZ amount. With increase of the BZ content, the (1 0 0)-preferential orientation and out-of-plane self-polarization of films enhanced. Because the 0.08 BZ film shows the higher self-polarization and lower KNN content, compared with 0.04 BZ film, it shows the stronger piezoelectric response but not a higher dielectric constant. © 2021

Abstract :

Environment-friendly lead-free piezoelectric materials with excellent piezoelectric properties are needed for high-frequency ultrasonic transducer applications. Recently, lead-free 0.915(K0.45Na0.5Li0.05)NbO3-0.075BaZrO 3-0.01(Bi0.5Na0.5)TiO3 (KNLN-BZ-BNT) textured piezo- electric ceramics have high piezoelectric response, superior thermal stability, and excellent fatigue resistance, which are promising for devices applications. In this work, the KNLN-BZ-BNT textured ceramics were prepared by the tape-casting method. Microstructural morphology, phase transition, and electrical properties of KNLN-BZ-BNT textured ceramics were investigated. High-frequency needle-type ultrasonic transducers were designed and fabricated with these textured ceramics. The tightly focused transducers have a center frequency higher than 80 MHz and a -6-dB fractional bandwidth of 52%. Such transducers were built for an f-number close to 1, and the desired focal depth was achieved by press-focusing technology associated with a set of customer design fixture. Its lateral resolution was better than 90 mu m by scanning a 15-mu m tungsten wire target. These promising results demonstrate that the lead-free KNLN-BZ-BNT textured ceramic is a good candidate for high-frequency ultrasonic transducer applications.

Abstract :

Magnetoelectric (ME) composites of bulk structures show strong ME coupling performance, and thus magnetoelectric bulk composites and their related devices have been attracting increasing attention over the last few years. Two kinds of ME coupling mechanisms can be found in ME bulk composites, i.e., direct ME coupling and converse ME coupling, where electric field control of magnetization or magnetic field control of ferroelectric polarization can be achieved. Then, ultra-fast, low-power, and miniaturized electronics can be developed based on the novel functionalities of both direct and converse ME coupling effects. Direct ME coupling is used in devices such as ME sensors and energy harvesters, while converse ME coupling is used in voltage tunable inductors, bandstop filters, ME antennas, tunable resonators, etc. Here, we present a review of bulk structure ME composite materials, as well as some notable potential applications of ME composites, with emphasis on both the opportunities and challenges for the application of ME composites. The performance of ME bulk composites, their coupling structures, state-of-the-art device applications, and perspectives on direct (magnetic to electric) and converse (electric to magnetic) ME devices are summarized.

Oxygen vacancy induced phase and conductivity transition of epitaxial BaTiO3-δfilms directly grown on Ge (001) without surface passivation EI SCIE
期刊论文 | 2021 , 129 (4) | Journal of Applied Physics
Abstract&Keyword Cite

Abstract :

The heterogeneous epitaxial system of BaTiO3/Ge (BTO/Ge) is of great interest for both fundamental research and device applications, thanks to its quasi-lattice-matching feature and the integration of functional oxides on semiconductors. Currently, the heteroepitaxial growth of crystalline BTO films on Ge includes the utilization of ultrahigh vacuum tools and complex surface passivation pre-treatment as well as careful control of oxygen partial pressure during the growth. Meanwhile, oxygen vacancies in oxides strongly impact their structural and electrical properties. Here, we report a facile method to directly grow single crystalline BTO films on Ge using pulsed laser deposition. The strict control of oxygen partial pressure ensures a sharp interface with an atom-to-atom registry and also leads to the oxygen-deficient characteristics of BTO. The epitaxial relationship of BTO and Ge is [110] BTO (001)//[100] Ge (001). Detailed crystallographic studies on BTO films with different thicknesses show that, for the films with a thickness less than 20 nm, BTO shows a mixture of tetragonal and cubic phases due to the oxygen vacancies and the strain from the Ge substrate and the cubic phase eventually dominates as the film thickness increases. Such oxygen-deficient BTO films reveal conducting characteristics rather than dielectric properties. The oxygen vacancies can be partly 'cured'after a low temperature annealing process. These results not only demonstrate the possibility to directly grow single crystalline oxides on semiconductors without surface passivation but also highlight the importance of oxygen vacancies and lattice strain on the crystallographic and electrical properties of BTO films. © 2021 Author(s).

Abstract :

Mutiferroic materials like bismuth ferrite BiFeO3 have attracted much interest in the last decade due to their promising potential for such applications as spintronics and magnetoelectric data storage devices. On the other hand, relaxor ferroelectrics have been intensively studied for their complex structures with quenched disorder and polar nanoregions which play an important role in their outstanding piezoelectric performance. Much less studied are the single-phase multiferroics that exhibit ferroelectric and/or magnetic relaxor behavior and the correlation between their structure and intricate magneto-electric interactions. In this work, we investigate the evolution of the structure and relaxor behavior in the solid solution between the complex perovskite multirelaxor Pb(Fe2/3W1/3)O3 [PFW] and canonical multiferroic BiFeO3 [BFO], (1-x)PFW-xBFO (with a solubility limit of x = 0.30). The temperature dependences of the dielectric permittivity and loss tangent measured in the frequency range from 100 Hz to 1 MHz indicate characteristic relaxor ferroelectric properties for compositions of x ≤ 0.15, with a frequency-dependent dielectric permittivity peak and its temperature, Tm, satisfying the Vogel-Fulcher law. Detailed studies of the evolution of the relaxor behavior with composition reveal that Tm decreases firstly with a small amount (x = 0.05) of BFO substitution and then increases with further increase of BFO concentration. The degree of relaxor character, as defined by ΔTm [Tm (1 MHz) - Tm (100 Hz)], increases monotonously with increasing BFO content, signifying an enhancement of relaxor behavior with BFO substitution, which is confirmed by the Lorenz-type quadratic variation of the static permittivity. A temperature - composition phase diagram is constructed in terms of the characteristic Burns temperature (TB) and freezing temperature (Tf), which delimits a paraelectric state (PE) above TB, a non-ergotic relaxor state (NR) below Tf, and an ergotic relaxor state (ER) in between. The observed enhancement of relaxor behavior is explained by an increase in the number and size distribution of polar nanoregions in the ER phase, resulting from increased compositional and charge disorders as a result of BFO substitution. The evolution of relaxor behavior and its microscopic mechanisms studied in this work are insightful for a better understanding the multirelaxor properties in multiferroics. Moreover, further substitution of BFO (x ≥ 0.2) flattens the permittivity curves and leads to a temperature-stable variation of high dielectric constant (≈ 103) in a wide temperature range, making the PFW-BFO solid solution attractive for such applications as high energy density capacitors. © 2020 Elsevier Ltd

Abstract :

Multiferroic materials have attracted much interest in the last decade due to both the intriguing fundamental science and the potential applications in spintronics and magnetoelectric data storage devices. In this work, we have investigated and discussed the evolution of the magnetic properties of the multiferroic (1-x)Pb(Fe-2/3 W-1/3)O-3-xBiFeO(3) solid solution ((1-x)PFW-xBFO, x = 0, 0.025, 0.05, 0.075, 0.1 and 0.15). The magnetic phase diagram is established based on the magnetic measurement results, which reveals six magnetically ordered states on the PFW-rich side of the solid solution. The origins of the complex evolution of magnetic order in the PFW-BFO solid solution are discussed from the point view of the variations in both the -Fe-O-Fe- and -Fe-O-W-O-Fe- superexchange routes, which are intimately related to the ratio of magnetic Fe3+ ion concentration on the B-site and the changes in the local structural order/disorder and chemical homogeneities. Combining the magnetic phase diagram with the relaxor characteristic phase diagram of the (1-x)PFW-xBFO system, a striking feature is found that the ergodic relaxor (ER) state and the weakly ferromagnetic phase coexist in the composition range of 0.025 <= x <= 0.1 between the freezing temperature T-f and the Burns temperature T-B.

Abstract&Keyword Cite

Abstract :

Bismuth calcium tantalate (CaBi2Ta2O9) ferroelectric ceramic has not been studied adequately though it shows potential applications in high-temperature piezoelectric devices due to its ultrahigh Curie temperature (T-C similar to 929 degrees C). In this paper, (Li0.5Pr0.5) co-substitution at A site was proposed to increase piezoelectricity activity (d(33)) and electrical resistivity (rho) of CaBi2Ta2O9-based ceramics and thereby a study of effect of the co-substitution on their structure and electrical properties was conducted. The composition Ca1-x(Li0.5Pr0.5)(x)Bi2Ta2O9+delta for x= 0.04 shows the highest d(33) of 15.1 pC/N which is about twice than that of CaBi2Ta2O9. At 700 degrees C, rho of this composition reaches up to 1.5 M Omega cm and hence the dielectric loss (tan delta) is lower than 3%. These results combined with high T-C (similar to 925 degrees C) and stable d(33) (up to 800 degrees C), suggest that it is a very promising material for high-temperature piezoelectric applications at 700 degrees C or higher.

Abstract :

Single-phase multiferroic BiFeO3-based perovskite solid solutions attract great research interest due to the coexistence of ferroelectric and magnetic orderings above room temperature. In this work, the single crystals of the 0.5(Bi0.9Dy0.1)FeO3-0.5PbTiO(3) ternary system are successfully grown and their structure and ferroic properties are characterized by a variety of techniques. X-ray diffraction reveals the tetragonal crystal structure. The ferroelectric Curie temperature is found to be approximate to 670 K from the dielectric and thermal measurements. The domain structures on multiple scales are investigated by polarized light and atomic force and piezoresponse force microscopies on the 001 orientated single crystals. Hierarchical domain configurations are revealed and explained based on the mechanical/electrical compatibility principles. The a-a- and a-c-type 90 degrees domains are widely distributed with size from sub-micrometer to dozens of micrometers. The domain evolutions after poling with various applied electric fields have also been investigated. Saturated ferroelectric hysteresis loops are obtained at room temperature with a remanent polarization of 9.0 mu C/cm(2). The Mossbauer spectroscopy investigations demonstrate the multiple local states of magnetic Fe3+ ions. The room-temperature paramagnetic nature develops into an antiferromagnetic order at T-N = 55 K. The findings of multiferroic domain walls give rise to the Dy-BFPT single-crystal potential for the domain wall nanoelectronics.

Bipolar Light-Addressable Potentiometric Sensor Based on Fullerene Photosensitive Layer EI SCIE
期刊论文 | 2021 , 6 (8) | ADVANCED MATERIALS TECHNOLOGIES
Abstract&Keyword Cite

Abstract :

Light-addressable potentiometric sensor (LAPS) is highly attractive in many sectors, including human disease detection, drug screening, and environmental monitoring. Currently, classical LAPS chips adopt inorganic semiconductors, such as silicon, as the photosensitive layer. Organic semiconductors can provide the next generation of the photosensitive layer because of their high absorption efficiency, large structural variability, eco-friendliness, and bendability. However, no promising organic materials have been reported so far for the construction of LAPS chips. Here, the authors demonstrate the potential of fullerene (C-60), a pi-conjugated carbon molecule with high n-type conduction, as a candidate material for the photosensitive layer of LAPS. They report on a peculiar bipolar photo-response under both reverse and forward biased conditions for C-60-based LAPS. An oxygen-trap-induced space-charge mechanism is proposed to explain the unique bipolar photo-response phenomenon. The proposed C-60-based LAPS exhibits an excellent pH sensitivity of 150 mV/pH as well as a high spatial resolution of 3.8 mu m. The authors anticipate that these results will spark interest in this field and enable the replacement of the inorganic-semiconductor photosensitive layer by organic semiconductor materials for the construction of high-performance LAPS.

A wearable, nozzle-diffuser microfluidic pump based on high-performance ferroelectric nanocomposites EI SCIE

Abstract&Keyword Cite

Abstract :

New target applications for microfluidic devices have been focused on home usability, wearability and cost-effectiveness. Towards these goals, in this work, a controllable, bendable, and all-organic, nozzle-diffuser microfluidic pump was designed, fabricated and tested. First, to resolve the crucial issue of high driving voltage, the ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) was optimized by adding core-shell structured Al2O3@CNT nanofillers. The membrane so developed with 1.1 wt% Al2O3@CNT showed an increase by nearly 7 times in the induced strain in comparison to the neat P(VDF-TrFE) at low electric fields, because the modified membrane simultaneously achieved a lower coercive electric field and a higher polarization. Accordingly, the required operating voltage of the microfluidic pump integrated with optimized membrane significantly decreased from 1000 V to 160 V. Meanwhile, this pump exhibited a wider range of flow rates (13-135 mu L/min) than the reported results, associated with the higher output pressure in our membranes. Importantly, the designed pump still possessed an excellent controllability of the fluidic processes, though it underwent a large bending up to 74 degrees. Consequently, the extremely promising application of the as-prepared microfluidic pump in wearable, biomedical devices was demonstrated.
