A pulse plating method for the electrosynthesis of ZnSe

A pulse plating method for the electrosynthesis of ZnSe Polycrystalline, thin films of ZnSe semiconductor compound were formed by cathodic electrodeposition from acidic aqueous selenite solutions of zinc sulphate, by using a potentiodynamic technique involving the application of repeated double pulses of controlled potential. Conditions for obtaining coherently uniform deposits with enhanced ZnSe to Se ratios were specified, on the basis of X-ray diffraction (XRD) and scanning electron microscopy results, by investigating the combined effect of the potential and length of each pulse as determined by duty cycle and frequency. It was shown that pulse plating process is a viable alternative to potentiostatic electrodeposition allowing improved control of the solid phase composition. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Electrochemistry Springer Journals

Abstract

Polycrystalline, thin films of ZnSe semiconductor compound were formed by cathodic electrodeposition from acidic aqueous selenite solutions of zinc sulphate, by using a potentiodynamic technique involving the application of repeated double pulses of controlled potential. Conditions for obtaining coherently uniform deposits with enhanced ZnSe to Se ratios were specified, on the basis of X-ray diffraction (XRD) and scanning electron microscopy results, by investigating the combined effect of the potential and length of each pulse as determined by duty cycle and frequency. It was shown that pulse plating process is a viable alternative to potentiostatic electrodeposition allowing improved control of the solid phase composition.
