Abstract
In situ ballistic-electron-emission microscopy (BEEM) has been perform ed at 77 K on partially strain-relaxed, epitaxial CoSi2/Si(111) films grown by molecular beam epitaxy. Hot electron scattering at individual interfacial dislocations has been observed for the first time by BEEM . Standing wave formation in the metal and changes of the surface elec tronic structure give rise to significant contrast in BEEM images. Apa rt from the dislocation- and surface-induced contrast, the interfacial transmission is generally found to be homogeneous.
