Abstract
Angle-resolved inverse-photoemission spectra have been measured on the nonreconstructed As:Si(111)-1 X 1 surface along the two main directio ns GAMMAKBAR and GAMMAMBAR of the surface Brillouin zone. We observed three empty bands, the lower one of which is characteristic of a surfa ce state partly resonant with bulk states in good agreement with theor etical calculations. We also observed a marked asymmetry in the disper sion along the M'GAMMAMBAR direction.
