Luminescence from InAsGaSb superlattices
Abstract
We present luminescence experiments performed in InAsGaSb superlattices as a function of temperature. In addition to radiative recombination between the electron and hole ground subbands, the luminescence spectra exhibit a low-energy tail below 300 K, which leads us to consider simple theoretical models to account for impurities and interface defects in superlattices. © 1981.
