Paper Title:
Size Effect on the Bandgap of Semiconductor Nanocrystals
  Abstract

The size-dependent valence-conduction bandgap of semiconductor nanocrystals are predicted based on a model for size-dependent cohesive energy, without any adjustable parameter. The model predicts an increase of the bandgap of semiconductors with decreasing crystalline sizes. It is found that the model predictions are in good agreement with the available experimental results for Si, ZnS, ZnSe, CdS, and CdSe nanocrystals.
