Paper Abstract

A microscopic theory of radiative recombination including the effects of photon reabsorption has ben developed which does not make the traditional assumptions of spherical constant energy surfaces, Maxwell-Boltzmann statistics for carriers, and constant momentum matrix elements. Numerical results illustrating the effects of photon recycling will be discussed for superlattice and bulk infrared detector materials. The calculations employ realistic K.p band structures and matrix elements. The lifetime enhancement can be greater than an order of magnitude.
