An investigation of GaAs surface modification under ion bombardment has been carried out using low-energy (10 keV) Ar and N ion implantation and studying the electrical characteristics of subsequently formed Schottky barrier devices. The GaAs surface barrier is altered for ion doses as low as 1012 cm-2 and the barrier is found to decrease for n-GaAs and increase for p-GaAs under bombardment from either implant species. The ion bombardment is also found to cause significant carrier compensation, resulting in series resistance and shunt conductance.
