Photo-f.e.t. method: high-resolution deep-level measurement technique using a m.e.s.f.e.t. structure

Abstract

M.E.S.F.E.T.s with channels produced by diffusion from spun-on emulsion films into semi-insulating GaAs were investigated by a new technique: the photo-f.e.t. method. The advantage over the commonly used photocapacitance method is outlined and measurements are presented.
