Abstract

The optical absorption, reflection and luminescence of CdTe:Ca were studied. It was established that the obtained Ca doped surface layers are characterized by intense photoluminescence from η = 8-10% in the edge region. Radiation is formed due to interband recombination of free charge carriers and the annihilation of excitons bound on isovalent impurities of Ca. The indicated components are observed in the differential optical reflection spectra ω in the surface layer obtained by doping CdTe substrates with an isovalent Ca impurity. It is established that doping causes the formation of p-type conductivity.
