Abstract

By using NH₄F/H₂O₂ as the surface passivant for p-CZT crystals, the C-V characteristics of p-CZT wafers before and after passivation surface treatments are investigated comparatively. After the passivation treatment, TeO₂ oxide layer with the thickness of about 3.1 nm is obtained on the surface of CZT wafer through XPS analysis. C-V test of CZT wafers is carried out by using Agilent 4294A Precision Impedance Analyzer with the frequency of 1 MHz. The results show that passivated CZT wafer has higher barrier height, i. e. , the barrier height of passivated CZT wafer is 1.512 V while that of non-passivated CZT wafer is 1.393 V.
