Abstract
A full scale microscopic calculation of Auger rates is performed on Si xGe1-x/Si superlattice structures with widely different parameters. We show that Auger rates are reasonably independent of superlattice para meters with Auger rates of some two orders of magnitude larger than th at of bulk silicon. Bandstructure is found to be the dominant factor i n the calculation and a simple geometrical model is devised to investi gate different types of structure. (C) 1998 Elsevier Science B.V.
