Study of surface photovoltage spectrum in p+-GaAs/p-GaAlAs/p-GaAs structures

Surface photovoltage (SPV) in p ^+ -GaAs/p-GaAlAs/p-GaAs has been studied by establishing a multilayer model and measuring the SPV at room temperature. The model mainly considers surface recombination velocity, interface recombination velocity and the space charge region (SCR) at the surface of p ^+...
