HYDROGEN-RELATED PHOTOLUMINESCENCE IN CDTE

Nominally undoped CdTe was exposed to a hydrogen plasma at 160 degrees C. After this treatment, seven typical photoluminescence lines are ob served in the excitonic region. By implantation with low-energy Hf all seven lines are also observed. They are assigned to the presence of h ydrogen in CdTe. Substituting deuterium for hydrogen, the isotope shif ts of these lines were investigated. Within the experimental resolutio n of 0.05 meV no isotope shifts are visible.
