The gain behavior of GaAs photoconductors realized on the partly compensated channel of a MESFET is studied. The gain versus light power dependence hints at the domination of the bimolecular recombination and the trap-mediated gain, and only a minor role of the surface photovoltaic effect. The possible correlation between dark current and gain mechanism is pointed out. |
