Paper Abstract

The physical processes in a two-dimensional electron gas (2DEG) driven into a nonequilibrium state by light illumination or increased microwave power are studied by combined optical and dimensional magnetoplasma resonance (DMPR) spectroscopies. A hysteretic DMPR, an optical bistability of the exciton and 2DEG Photo-luminescence, an evolution of the photoexcited electron-hole system from exciton to metal state in modulation doped and undoped heterostructures are investigated.
