Влияние режимов формирования контактной системы Pd/Ge/Au к n-GaAs на ее электрические характеристики

Abstract

The investigations of Pd/Ge/Au contact system forming regimes influence on the specific contact resistivity to n-type conductivity GaAs layer were carried out. The method of samples surface treatment before the layers evaporation and thermal annealing regimes in H2, N2 and Ar atmosphere influence on contact system parameters was investigated. The specific contact resistivity value 2-3•10-6 Ohm•cm2 at the reduced annealing temperature 190 C was archived.
