Abstract
- Optically detected and conventional spin resonance investigations have been successful in determining the structure of cation vacancy-donor pairs (A-centers) and anion vacancies ( V Te ) in CdTe. Investigations in the ternary alloy systems Cd1−xZnxTe for the complete range of x show that the A-center binding energy is almost independent of the composition. In CdTe the VTe+/0 level position is 0.2 eV above the valence band and correlation to a deep luminescence band at 1.15 eV can be drawn. In the alloys this photoluminescence band closely follows the conduction band from CdTe to ZnTe. Studies of the spectroscopic g- values of the shallow donors in Cd 1−x Zn x Te show that they shift linearly from -1.69 in CdTe to -0.4 in ZnTe.
