Abstract
The transient response of semi‐insulating CdTe to monoenergetic alpha particles is composed of a fast component, characteristic of trapping, and slow component displaying the release of carriers from traps. It is verified that the shape of the fast component is directly proportional to [1 ‐ exp (‐t/τ+)] for electrons where τ+ is the mean free drift time. From an analysis of the shape, τ+ for electrons ranges from 30 to 90 nsec; mobilities from 600 to 1100 cm2/V‐sec. On a single‐level model thermal and optical excitation data indicate a trapping level at 0.6±0.05 eV from the conduction band.Keywords
