Gn. Henderson et al., QUANTUM TRANSMITTANCE FROM LOW-TEMPERATURE BALLISTIC-ELECTRON-EMISSION SPECTROSCOPY OF AU SI(100) SCHOTTKY INTERFACES/, Physical review letters, 71(18), 1993, pp. 2999-3002
Ballistic electron emission microscopy studies of the Au/Si(100) inter
face have been performed at temperatures below 77 K for the first time
. Spectra below 10 K show collector charging due to the high semicondu
ctor resistivity. Results above 10 K demonstrate unambiguously that bo
th quantum-mechanical phase and amplitude effects are required to desc
ribe electron transmission across a metal-semiconductor interface. Fur
thermore, the ballistic (collisionless) model of electron transmission
across this interface is shown to be valid for a wide energy range.
