Abstract

The fundamental properties are investigated of diodes formed by evaporation of gold on polished and etched surfaces of n-CdTe. I–U characteristics measured at temperatures of ≈ 130 to 300 K and C–U characteristics can be explained by Schottky's theory of the metal–semiconductor contact with recombination in the space charge region. A barrier height of 0.8 to 0.9 eV is determined from the I–U characteristics, and by means of the spectral dependence of photoemission current. An aging effect of the diodes caused by a decrease of donor concentration is ascribed to diffusion of oxygen. The barrier height is probably determined by surface states forming an inversion layer at the metal–semiconductor interface. [Russian Text Ignored]
