Electrochemical formation and photoelectrochemical characterization of (CdHg)Se films

Abstract

(CdHg)Se films of variable composition have been prepared using electrochemical codeposition. Photoelectric activity and current–voltage studies in the dark and under illumination revealed the formation of n- and p-type electrodeposits. The functional activity of these electrodeposits depends on the speed with which the current decreases during electrochemical codeposition under potentiostatic control. Photoaction spectral studies were used to investigate the effect of the inclusion of mercury on the bandgap of the electrodeposits. X-Ray diffraction and scanning electron microscopic studies have also been performed.
