【Abstract】 The variations on composition of electrodeposited CdTe thin films withcathodic potentials,electrolyte temperatures and heat treatment temperatures were studiedby using polarographic method.The CdTe thin films where the Cd/Te atomic ratio equalunity was obtained at a potential about-0.6V vs SCE and electrolyte temperature below50℃.The change of semiconductivity of the CdTe films was observed by heat treatment.While p-CdTe films were favourably prepared at temperature lower than 300℃,n-CdTefilms were obtained only above 350℃.更多还原
