The electrical resistance of a single crystal of cadmium sulfide was measured at pressures up to 40 kbar and at temperature up to 700℃ in a cubic compact anvil high pressure apparatus. The electrical conductivity of CdS of either the atmospheric wurtzite phase or the high-pressure rock salt phase is semiconductive. In the high-resistivity samples used in the present experiment the electrical resistance increased with pressure in either phases, the wurtzite or the rock salt. From the measurements of electrical resistance as a function of temperature, it is found that a band gap of CdS of the wurtzite phase is about 2.5 eV. for the CdS of the rock salt phase a band gap of about 0.8 eV is obtained.
