Abstract

Cadmium Sulfide (CdS) thin films had been fabricated by a laser deposition technique. Our previous results indicated that the hexagonal structured films could be formed at a substrate temperature of 400 C or higher. Reducing the temperature to 200 C or lower, cubic dominant films had been fabricated. To further understand the effects of other deposition parameters, CdS films were deposited at 30 C in this study. Crystal structures of the films were analyzed by Xray diffraction (XRD) and Transmission Electron Microscopy (TEM). It was found that the processing windows for the cubic films were very limited. As revealed by optical transmission measurements, the optical absorption edge of the cubic film was different from that of the hexagonal film.
