Picosecond time resolved photoemission study of the InP(110) surface.
01 January 1985
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 gamma (bar) and the surface band dispersion near gamma (bar) (effective mass) was measured along two surface symmetry directions.
