Optical characterization of a Cd(0.85)Mg(0.15)Se mixed crystal.

We present an optical characterization of a Bridgman-grown wurtzite-type Cd(0.85)Mg(0.15)Se mixed crystal in the near-band-edge interband transitions using temperature-dependent contactless electroreflectance (CER) and photoreflectance (PR) in the temperature range 15-400 K.
