Energy gap: 2.4ev.
The colour of pure cadmium sulphide is pale yellow. It melts only under at high temperature. It can be prepared in the resistivity range from 10 to about 1012Ω-cm depending on the presence of defects and the impurities. it can be prepared as an semiconductor device and is extremely difficult to produce P-type cadmium sulphide. It has been used commercially as a photo conductor for many years as well as constituent of cathode ray phosphorous.
At high reverse voltage, due to high electric field, the minorities charge carriers, while crossing the junction acquires very high velocities. A chain reaction is prepared, giving
