Near-band-gap photoluminescence of Hg1−xCdxTe

Abstract
The results of photoluminescence studies of Hg1−xCdxTe with x=0.32 and 0.48 for temperatures between 5 and 30 K are described. In the x=0.32 and x=0.48 material, band‐to‐band, band‐to‐acceptor, and donor‐to‐acceptor luminescence lines are observed. We report the first observation of bound‐exciton luminescence in HgCdTe, which we observe in the samples with x=0.48.
