Electrical and Optical Properties of CdS Films Grown by Photochemical Deposition From Aqueous Solutions

Abstract
Recently, we have established a novel deposition technique for semiconductor thin films, namely photochemical deposition (PCD), in which the compound formation is activated by ultraviolet illumination. In the present work, the electrical properties of the PCD-CdS films grown under different conditions are analyzed and presented. Their resistivity is high at room temperature and decreases with increasing temperature with an activation energy of about 0.9 eV.
