DLTS Study of Pulsed Ruby Laser Irradiation Effects on n-CdTe

Abstract
DLTS measurements were carried out for Au/n-CdTe junctions which were formed on surfaces irradiated by a pulsed ruby laser. Electron trap levels at 0.65 eV and 0.83 eV below the conduction band were induced in high concentration by the irradiation of more than 0.8 J/cm2 energy density. The irradiation of 0.3 J/cm2 improved the characteristics of Schottky junction of Au/n-CdTe and ohmic contact of In/n-CdTe.
