摘要
The response of local Schottky barriers (SB) to local specifics of the interface is readdressed by photoelectron microscopy investigations of metal/GaN interfaces, which reveal that compositional and morphological inhomogeneities have no effect on local SB heights. This unexpected behavior is ascribed to lateral charge redistribution between different interface regions leading to homogenization of the SB fluctuations at the semiconductor surface in contact with the metallic layer.
