Paper Abstract

We present a study of the excitonic luminescence contribution in Hg1-xCdxTe for a wide CdTe mole fraction range (0.23 < x < 0.97). This mixed crystal semiconductor system is relatively well understood and offers a unique possibility to study the contribution of excitons to the luminescence of a material with a continuously decreasing energy gap. This reexamination is based on a set of uniform (carrier concentration, degree of compensation) samples grown by the traveling heater method. Furthermore the luminescence from Hg0.15Cd0.85Te/Hg0.7Cd0.3Te superlattices is analyzed with respect to the luminescence contributions of confined 2D excitons.
