We report the first use of angle-resolved ultraviolet-photoemission spectroscopy to study electron dynamics in the picosecond time domain on a photoexcited semiconductor surface. Transient population in a normally unoccupied surface state on InP(110) was directly observed. The band minimum for this state was found to lie at Γ̅ and the surface-band dispersion near Γ̅ (effective mass) was measured along two surface symmetry directions.
