Present investigation explores the possibilities of surfactant facilitated colloidal HgS particulate inclusion during the electrodeposition of ZnSe semiconductor film. inclusion of colloidal particles was inferred on the basis of current-voltage, photoaction spectral studies and as well as absorption studies of colloidal HgS suspensions. Tafel plots were constructed for the examination of corrosion behaviour of the electrodeposited composites. The results show that inclusion of colloidal HgS particles improves the photoactivity and electrochemical corrosion of the ZnSe semiconductor films. (C) 2009 Elsevier B.V. All rights reserved.
