Surface Photoconductivity of Cadmium Sulphide modified with Magnetic Field

Abstract

An experiment on the changes of photocurrent in cadmium sulphide single crystals in magnetic field was performed. The results obtained are as follows; the changes of photocurrent by magnetic field are dependent on the strength of electric and magnetic fields which are parallel to the illuminated surface and are perpendicular to each other, and the changes are also dependent on the frequency of the alternating electric field, the wavelength of illuminating light and on the ambient atmosphere, while these changes are independent of the intensity of illuminating light. Some theoretical treatments based on the phenomenological theory of surface recombination are proposed with these experimental results, and they seem to give some informations about surface recombination of cadmium sulphide single crystals.
