Calculation of the band gap for small CdS and ZnS crystallites
P. E. Lippens,Michel Lannoo +1 more
TL;DR: In this article, the size dependence of the band gap for small CdS and ZnS crystallites (20-2500 atoms) was studied using a simple model of the crystal, which has no dangling bonds and a symmetrical shape.
Journal Article
Calculation of the band gap for small CdS and ZnS crystallites
P. E. Lippens,Michel Lannoo +1 more
TL;DR: The tight-binding approximation and the recursion method are used to study the size dependence of the band gap for small CdS and ZnS crystallites and determine the peak position from a simple evaluation of the binding energy.
Journal ArticleDOI
Comparison between calculated and experimental values of the lowest excited electronic state of small CdSe crystallites
P. E. Lippens,Michel Lannoo +1 more
TL;DR: On considere deux types de forme cristalline et une constante dielectrique variant dans l'espace d'analyses en bon accord avec les experiences recentes.
