Abstract
The relaxation of photoexcited electrons and holes at surfaces of GaP( 110) was studied by means of two- and three-photon photoelectron emiss ion under 3.16 eV photon excitation. With 200 fs time resolution, only the relaxation of surface states within the bulk band gap could be re solved occurring with time constants of 0.3 and 2.5 ps.
