Abstract :
A GaAs-InGaAs optoelectronic switch, grown by molecular beam epitaxy (MBE), has been fabricated. Owing to the avalanche multiplication and hole accumulation in the transport mechanism, bistable states, i.e., a high-impedance OFF state and a low-impedance ON state, are observed in the current-voltage (I-V) characteristics. The device shows a flexible optical function related to the potential barrier height controllable by incident light. The dependence of the I-V characteristics on illumination is attributed to the photogenerated hole accumulation in the device operation.
