ELECTROREFLECTANCE AND THERMOREFLECTANCE OF ZnSiAs2

Abstract
Measurements of electroreflectance as a function of temperature in the range 195–350°K and of thermoreflectance at room temperature have been made on chalcopyrite‐type ZnSiAs2 in the energy range 1.9–3.5 eV. The identification of the various peaks in the E0 and E1 complexes is discussed and the temperature coefficient of the various transitions determined.
