Abstract：

To　understand　the　effects　of　tellurium　(Te)　inclusions　on　the　device　performance　of　CdZnTe　radiation　detectors,　the　perturbation　of　the　electrical　field　in　and　around　Te　inclusions　was　studied　in　CdZnTe　single　crystals　via　Kelvin　probe　force　microscopy　(KPFM).　Te　inclusions　were　proved　to　act　as　lower　potential　centers　with　respect　to　surrounding　CdZnTe　matrix.　Based　on　the　KPFM　results,　the　energy　band　diagram　at　the　Te/CdZnTe　interface　was　established,　and　the　bias-dependent　effects　of　Te　inclusion　on　carrier　transportation　is　discussed.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
