The InAs(110) cleavage surface is studied by photoelectron spectroscopy based on an amplified short-pulse titanium:sapphire laser system in both probe-only and pump-and-probe modes. The probe-only spectra show that electrons accumulate in the conduction band at the surface as a function of time after cleavage, while the pump-and-probe spectra show a different response from the excited accumulation layer peak when using s- and p-polarized probe pulses. Moreover, no surface photovoltage is detected when the accumulation layer is optically pumped. (C) 1998 Elsevier Science B.V. All rights reserved.
