摘要

Using an sp(3)s* empirical tight binding method, we calculate energy band gap and electronic band structure of the zinc-blende ternary alloy ZnSxSe1-x. The band gap composition is calculated using an extended version of the virtual crystal approximation, which introduce an empirical correction factor that takes into account the non-linear dependence of the band gap with the composition. The results compare well with the experimental data. The ionicity character and the refractive index are also calculated. (C) 2003 Elsevier B.V. All rights reserved. [References: 32]
