A. Dicarlo et al., SELF-CONSISTENT TIGHT-BINDING CALCULATIONS OF ELECTRONIC AND OPTICAL-PROPERTIES OF SEMICONDUCTOR NANOSTRUCTURES, Solid state communications, 98(9), 1996, pp. 803-806
Optical properties and electronic states of semiconductor nanostructur
es are calculated by using tight-binding models which account for vale
nce band mixing, strain and external applied potentials in a self-cons
istent fashion. An appropriate formulation of the optical susceptibili
ty in the tight-binding basis is given without introducing-any additio
nal parameters. Results for strained and unstrained systems are given.
