Photovoltaic Effect in Ohmic Metal-Semiconductor Structures Excited by Femtosecond Laser Pulses

Photovoltage 2D mapping of low-temperature GaAs metal-semiconductor-metal micro-structures reveals thermovoltaic and photovoltaic effects with the former being the dominant process at high average power for both cw and femtosecond-pulse excitations.
