Abstract

We have studied the ability of different oxidizing agents, other than H₂O₂ to reduce the surface leakage current of CdZnTe devices. All chemical treatments were performed in aqueous solutions, at room temperature, with weight percent concentrations of 2.5 g/25 ml. Before and after I-V curves were obtained. It was found that by increasing the basicity of the chemical treatment, greater reduction in surface leakage current occurred. The results show that these alternative chemical treatments reduced the surface leakage current as well as or better than H₂O₂ chemical treatment.
