Tight-binding analysis of the structural dimension dependence of the optical bandgap in ZnSe/ZnS core-shell quantum dots

The structural dimension dependence of the optical bandgap in ZnSe/ZnS core–shell quantum dots is examined using a valence force field model combined with an atomistic tight-binding approach. We demonstrate that increasing shell thickness enhances compressive strain within the Zn...
