Hysteretic drain current (Id) drift phenomena observed in the high power operation of WSi gate GaAs MESFETs were studied. The existence of a thin insulating layer at WSi/GaAs interface originated by the native oxide on GaAs surface was revealed by XPS and X-ray reflection. Id drift phenomena can be explained as the effect of holes being trapped in the insulating layer at the WSi/GaAs Schottky contact interface.
