Title: Influence of Surfactants and Charges on CdSe Quantum Dots

Abstract

The chemistry between CdSe quantum dots and common surface capping ligands is invested using density functional theory. We will discuss the electronic structures and optical properties of CdSe QDs controlled by the size of particle, self-organization, capping ligands, and positive charges. Charges on quantum dots have profound effects on their structures, binding energies, and optical properties.
