Potentiostatic condition of -250 mV against standard calomel electrodes (SEC) was used for the electro deposition, To convert the top layers of the CU20 to Cu.S by sulphidation, exposed the surface to a spray of aqueous solution of sodium sulphide or to a mixture of hydrogen sulphide and nitrogen gases to foam ITO/n-Cu20/p-CuxS system. For the system ITO/n-Cu2O/metal, metal layer was evaporated on to the n-Cu20 surface. An electrolyte of 0.1 M sodium acetate was used in the ITO/n-Cu20/electrolyte system. Electro deposition of ZnSe thin films were carried out under potentionstatic condition at -550 mV against SCE using aqueous solutions of 0.1 M ZnS04 and 10-5 M Se02 at the temperature of 65� C. The theoretical and experimental 1-V characteristics of ITO/n-Cu2O/(P-CuxS or metal or electrolyte) system suggest that CU20 films made on ITO substrate form Schottky type junctions at the back contact in addition to the CU20/(p-CuxS or metal of electrolyte) junctions. Furthermore, C-V characteristics suggest that the doping concentration of the CU20 layer is in the order of 10 18. Light and dark I-V measurements of doped and undoped lTO/ZnSe in KI electrolyte suggest the p-type photoconductivity in this system and C-V measurements confirmed it.Item Use of geographical system as a tool for fish yield prediction in tropical reservoirs : a case study on Sri Lankan reservoirs(University of Kelaniya, 2000) Nissanka, C.; Amarasinghe, U.S.; de Silva, S.S.
