Abstract

The BURSTEIN effect is observed in cadmium selenide single crystals doped with gallium, prepared from the melt, with electron concentrations in the range 10^18^ to 10^20^ cm^−3^. It is deduced from absorption and reflection measurements that both the energy gap and the crystald field splitting decrease with increasing electron concentration. Birefringence is found to decrease with increase of impurity concentration at room and liquid nitrogen temperatures.

The optical properties of Te doped GaP single crystals were investigated in the spectral range of 0.20-3.0 ~tm. It was found that the spectral distributions of R, n, er and a,. reflect sharp structure due to valence to conduction-band transitions (E,, E0, El and E2) having the energies 2.16,2.75,3.6
