Abstract
This paper presents the nonaqueous electrodeposition and characterisation o f CdxHg1-xTe films. Cyclic voltammetry and photovoltammetry were used to id entify the potential for CdxHg1-xTe deposition. Film composition and struct ure were analysed using XPS and XRD. Compositional analysis suggests replac ement of some cadmium by mercury in the CdxHg1-xTe films. Moreover, the inc orporation of mercury was also found to promote preferential orientation of (111) plane. Absorbance studies indicated a decrease in band gap from 1.47 eV for CdTe to 1.40 eV for Cd0.97Hg0.03Te. (C) 1999 Elsevier Science Ltd. All rights reserved.
