      abstract     = {We report on ballistic electron emission microscopy and
                      spectroscopy studies on epitaxial (3-5 nm thick) Bi(111)
                      films, grown on n-type Si substrates. The effective barrier
                      heights of the Schottky barrier observed are 0.58 eV for the
                      Bi/Si(100)-(2x1) and 0.68 eV for the Bi/Si(111)-(7x7). At
                      the step edges of the epitaxial films a strong increase of
                      the ballistic electron emission microscopy current is
                      observed for Bi/Si(111)-(7x7), while no increase occurs for
                      Bi/Si(100)-(2x1). These observations can be explained by the
                      conservation of the lateral momentum of the electron at the
                      metal-semiconductor interface.},
