Electron-Phonon Coupling in CdSe Nanocrystals

The coupling between nuclear vibrations and electronic excitations (electron-phonon coupling) in semiconductor nanocrystals influences many photophysical process in these materials. While electron-phonon coupling in CdSe nanocrystals has been studied both experimentally and theoretically for more than 20 years, there remains little agreement about its magnitude and size dependence. This perspective summarizes key litreature results suggests reasons for their disagreement, and proposes approaches to better determine this important quantity.
