Abstract

An excellent review of the electrical and optical properties of α-sulphur has been given by Moss. It is concluded that the conductivity is intrinsic and that the energy gap is approximately 2.5 eV, corresponding to a thermal activation energy of 1.3 eV. In this communication we present evidence that the energy gap in α-sulphur is 3.8 eV, both electrons and hole being mobile, and that the lower values previously reported are due to excitation from defect states within the crystal.
