Abstract
The evolution of the electronic structure of semiconductor quantum dots (QDs) with QD size in the strong confinement regime was demonstrated by employing low-temperature tunneling current-voltage spectroscopy to individual electrodeposited CdSe QDs. The values of Eg, map discrete energy levels in both valence and conduction bands were measured from the spectra. The occurrence of single-electron tunneling effects for isolated QDs of different sizes were shown.
