Quasi-lateral 2DEG2DHG junction in AlGaAs/GaAs
We report on an electrical and electroluminescence (EL) investigation of a quasi-lateral two-dimensional electron gas and two-dimensional hole gas junction based on an AlGaAs/GaAs heterostructure. Current bistability is demonstrated, leading to bistability in the EL efficiency.
