Abstract
Infrared transmittance and electrical properties of undoped and In-doped CdTe single crystals were investigated before and after post-growth annealing at high temperature followed by various cooling regimes. Typical free carrier absorption was found in the IR transmittance spectra at low energies.
Non-standard absorption behavior was observed in the range 0.8-1.5eV in samples,which were quenched in the air after annealing.
