    The work reports on the photocurrent (PC) study of diodes based on bulk semi-insulating (SI) GaAs with novel contacts including low work function metals, such as Gd and Nd. SI GaAs sandwich-like structures with topside electrodes of Gd/Au, Nd/Au, Pt/Au, and AuGeNi eutectic alloy and bottom AuGeNi eutectic alloy were fabricated. Their electrical and photoelectronic properties were investigated by current-voltage measurements and PC spectroscopy performed at room temperature in the spectral range of 600-1000 nm. A simple photovoltaic model was used to give a qualitative explanation of the observed spectral characteristics at zero bias.
