Abstract
Pronounced structure at large biases in the ballistic-electron-emission-microscopy (BEEM) current for Cr/GaP(110) is attributed to density-of-states effects in GaP. Quasielastic scattering at the Cr-GaP interface appears vital for the effect. Impact ionization in the GaP is invoked to explain the unusually large collector currents that can exceed the injected STM tip current.This publication has 20 references indexed in Scilit:
