Far Infrared Emission and Possibility of Population Inversion of Hot Holes in MQW TnGaAs/GaAs Heterostructures Under Real Space Transfer
Abstract
Far IR emission and current-voltage characteristics of hot holes in strained MQW In(x)Ga(1-x)As/GaAs heterostructures at lateral charge transport are investigated. Highly nonequilibrium phenomena observed are shown to results from the real space transfer. The simple experimental criterion for the population inversion between barrier and quantum well states is put forward. The population inversion is shown to realize in "shallow" (with respect to the optical phonon energy) In(x)Ga(1-x)As quantum wells.
