摘要：
In this paper, the CZT oxidized layers on cadmium zinc telluride (CZT) wafer formed by two-step chemical passivation process (KOH-KCl + NH(4)F/H(2)O(2)) were investigated by using XRD, ED-XRF, SEM. The results show that the oxidized layer obtained by using this process has a very uniform and compact morphology and consists mainly of TeO(2),, TeO(3) and CdTeO(3). In particular, the thickness of the oxidized layer on the CZT was obtained by using C-V measurements for the first time. The dependence of the thickness of the oxidized layer on the passivation time was obtained and the main factors influencing the results of the C-V measurements were also discussed.
