      abstract     = {A surface photovoltage (SPV) is observed whenever a doped
                      semiconductor with non-negligible band bending is
                      illuminated by light and charge carriers are excited across
                      the band gap. The sign of the SPV depends on the nature of
                      the doping, the amplitude of the SPV increases with the
                      fluence of the light illumination up to a saturation value,
                      which is determined by the doping concentration. We have
                      investigated Si(100) samples with well-characterized doping
                      levels over a wide range of illumination fluences.
                      Surprisingly, the sign of the SPV upon illumination with 532
                      nm photons reverses for some p-doping concentrations at high
                      fluences. This is a new effect associated with a crossover
                      between electronic excitations in the bulk and at the
                      surface of the semiconductor.},
