Paper Abstract

This article mainly deals with the exact origin of 0.15 - 0.20 eV defect level in CdTe--a controversial issue under debate for more than three decades--and some investigations of deep and interface levels in polycrystalline n-CdTe. The first issue still stands unresolved amidst conflicting views from various workers, thereby leaving it surrounded by an air of uncertainty. The results of a study of deep and interface states in Mo-polycrystalline n-Schottky barriers using a deep level spectrometer DLS-82E (Hungary), both in differential DLTS and level profile mode, are also presented. Three deep levels with activation energies of 0.2, 0.43 and 0.65 eV and capture cross-section of the order of 10-18 cm2 detected in the bulk of layers are discussed.
