Title: Structure having spatially separated photo-excitable electron-hole pairs and method of manufacturing same

Abstract

A method for producing quantum dots. The method includes cleaning an oxide substrate and separately cleaning a metal source. The substrate is then heated and exposed to the source in an oxygen environment. This causes metal oxide quantum dots to form on the surface of the substrate.
