Paper Abstract

Threshold characteristics of type II QW-lasers have been investigated theoretically. The rate of non-threshold channel of Auger recombination in type II heterostructures with quantum wells has been calculated. It is shown that the AR rate is a power function of temperature rather than an exponential one as in bulk materials. Feasibility of suppression of the Auger recombination process in the type II HS is demonstrated. The Auger current has a minimum and internal quantum efficiency has a maximum at a definite ratio of the barrier heights for electrons and holes. The possibility of controlling the AR current is shown to be very important for the creation of mid-infrared lasers operating at room temperature.
