Abstract

Enhancement of Schottky barrier height of Ti-Pt-Au on n-type GaAs was obtained by heavily (2×10¹⁸ cm^-3) counter doping the near-surface region of the substrate. The p-type region was produced by recoil implantation of Mg from a Mg thin film (300 Å) irradiated by a 60 keV As⁺ beam. The film was subsequently chemically etched. The recoil-implanted samples showed an enhancement of 140 meV in the Schottky barrier height following rapid thermal annealing in an AsH₃ furnace at 850°C for nominal zero second.
