Abstract
Wavelength modulated reflectivity spectra near the fundamental absorption edge of Cd1−xFexSe (0.01≤x≤0.07) solid solutions have been measured in the temperature range 8–300 K. A line‐shape analysis of the structures observed allows us to determine the temperature and composition dependence of interband transition energies. The energy gap varies linearly with composition in the range studied. The temperature variation of the energy gap can be well fitted by the empirical Varshni relation.This publication has 5 references indexed in Scilit:
