Voltammetric determination of electronic structure of quantum dots

Abstract

Electronic structure plays an important role in determining the physiochemical properties of semiconductor quantum dots (QDs). Fabrication of high-performance QD devices relies on the reliable determination of electronic structure of QDs. Voltammetry enables the easily accessible detection on the energy levels of QDs. Herein, the fundamentals of voltammetric detection are first reviewed and discussed. Since the common ways used for tailoring electronic structure of QDs include tuning size, surface engineering, and varying composition, we next summarize the recent research on using voltammetry for probing the energy levels when studying these three effects.
