摘要
Au, Ag, Al and Pd-InP (n type) interfaces were obtained by UHV and air cleavage. The interfaces were characterized by electrical methods: I-V, C-V, SCS (Schottky Capacitance Spectroscopy). In spite of great variations in the reactivities of the deposited metals and two kinds of interface preparation, the Schottky barrier heights (except air cleaved Au-InP) are quite similar. The study of interface states by SCS shows the presence of two characteristic states, regardless of which metal, localized near E(c)-0.25 eV and E(c)-0.37 eV. The latter may play a significant role in the Fermi level pinning.
