Abstract
Ballistic-electron-emission microscopy (BEEM) of Au and Mg films on n- type GaP(110), with thicknesses as low as 12 angstrom, reveals strong variations of spectral shape and magnitude of the BEEM current with me tal-film thickness and surface gradient. Using Monte Carlo simulations , the hot-electron transport between tip and semiconductor can be quan titatively described, providing detailed information on tunneling, tra nsport in the metal, transmission across the interface, and impact ion ization in the semi-conductor.
