Title: The energy band gap of cadmium sulphide
Authors: Boakye, F.

Publisher: Elsevier Science Ltd
Abstract: The energy band gap of cadmium sulphide has been determined for the bulk specimen and films prepared by thermal evaporation on glass sub- strates in vacuum. The energy band gap of the specimens were deduced from their temperature variation of their resistance in the intrinsic range. The results reveal higher energy gaps in the films than in the bulk specimen. The energy gap of the films increases from 2.46 eV typical of the bulk value to 3.24 eV as the substrate temperature is reduced from 200 to 30°C. The high energy gap at low substrate temperatures may be interpreted as due to a distorted structure in the cadmium sulphide film.
