Abstract

Schottky characteristics of electrical contacts to complex heterostructures consisting of intermediate semiconductor layers with various thicknesses and underlying bulk layers have been studied. For Au/InAlAs/InP structures, I-V characteristics with thin InAlAs layers are found to be similar to those of a MIS tunneling diode, while those with thick InAlAs layers are found to be close to that of Au/InAlAs. For Au/InP/InAlAs structures, a substantial current barrier are found to be formed not at Au/InP but at InP/InAlAs heterojunction. Schottky barrier height in the case of strained intermediate layers of In1-xGaxP is also discussed.
