Mechanism for a suppression of Auger recombination in type-II heterostructures
Andreev A. D. , Zegrya G. G.
The mechanism for Auger recombination in type-II heterostractures is studied theoretically for the first time. The rate of this recombination is a power-law function of the temperature, not an exponential function, as it is in the bulk material. A suppression of Auger recombination in type-II heterostructures is predicted. This suppression would stem from the short-range nature of the Coulomb interaction of the electrons involved in the recombination. A suppression of Auger recombination at type-II heterostructures has recently been observed experimentally.
