Abstract
The influence of the surface on photoexcitation under static electric fields is studied by measuring and calculating the Franz-Keldysh (FK) spectra from a surface space-charge region in InP. An optically inactive surface layer (OISL) is found to be indispensable in accounting for the FK spectra observed under surface electric fields up to about 200 kV/cm. The origin of OISL is discussed in terms of surface effects on the field-induced wave function of the excited state
