AbstractBy achieving electrostatic feedback due to hole accumulation in an asymmetric triple-barrier resonant tunneling light-emitting diode, inverted bistability is obtained in the current-voltage characteristics. In the low current state, the resonant electron current is suppressed, resulting in the absence of quantum-well light emission. When switching to the high current state, the sudden increase in electron population causes a steplike increase in luminescence which yields an optical on-off ratio larger than 104:1. This improvement by a least a factor of 1000 with respect to the existing double-barrier resonant tunneling light-emitting diodes makes the new triple-barrier structure drastically more appealing for bistable switching applications.
