Abstract

Accumulation of electrons and holes has been revealed by capacitance-voltage technique in As-cluster containing GaAs layers sandwiched between n-type or p-type GaAs buffers. As a result of the majority carrier accumulation, a large depletion region forms in adjacent buffers. Simulation of the capacitance-voltage characteristics based on numerical solution of the Poisson equation showed the concentration of accumulated charge to be as high as 1×1012 cm-2 which is comparable with the concentration of As clusters determined from transmission electron microscopy study.
