摘要:
Thin films of bismuth sulphide (Bi2S3) are deposited by a novel nebulised spray pyrolysis technique. The deposited films are characterized by X-ray diffraction, Scanning Electron Microscopy, EDAX, UV-Vis. Spectroscopy. Electrical and photoelectrochemical properties of the films are analysed by four probe resistivity and C-V measurements respectively. As-deposited films are amorphous and annealing of the films is found to improve the crystallinity of the film. Optical transitions involved in the material are found to be direct and allowed. The films recorded a room temperature resistivity of 20 Omega-m.
