Abstract

It has been shown that NH~3~, plasma treatment of GaAs surfaces before deposition of plasma‐enhanced chemical vapour deposited silicon nitride significantly improves the SiNH/GaAs interface properties. The decrease of surface state density together with the increase of Fermi level excursion in the energy gap are correlated with chemical spectroscopic measurements.
