Mechanism of suppression of Auger recombination processes in type-II heterostructures

Abstract

The mechanism of Auger recombination in type-II heterostructures is studied theoretically. It is shown that the Auger recombination rate is a power function of temperature rather than an exponential function as in bulk materials. The feasibility of suppression of the Auger recombination process in the type-II heterostructures is demonstrated. The possibility of controlling the Auger recombination rate is shown to be very important for development of optoelectronic devices with improved characteristics.
