Abstract
We describe a new semiconductor heterostructure, configured into a bistable device that can be switched either optically or electrically. The two states between which switching occurs involve very different levels of charge accumulation in a quantum well channel, affecting both the photoluminescence spectrum and the vertical photocurrent. The agents in the switching mechanism appear to be hot carriers.
