Abstract
We have performed in situ ballistic-electron-emission microscopy (BEEM ) and spectroscopy (BEES) at 77 K on epitaxial CoSi2/Si(111) films gro wn by molecular bearn epitaxy. The transport in the silicide was found to be essentially ballistic. With the help of atomic-resolution scann ing tunneling microscopy it has been found that the BEEM current depen ds significantly on the surface electronic structure. On strain-relaxe d layers, hot electron scattering at individual interfacial dislocatio ns has been observed for the first time by BEEM. Apart from the surfac e- and dislocation-induced contrast variations, the BEEM current is ge nerally homogeneous.
