✦ Synopsis
Since the crystal size of semiconductor quantum dots (QDs) affects the optoelectronic properties of QDs, a method of controlling the size is important. It is demonstrated that CdSe QDs electrodeposited epitaxially on {111} Au can be tuned from <5 to ∼ 20 nm by introducing small amounts of Te into the electrodeposited CdSe, i.e., by decreasing the mismatch between the deposited layer and the substrate. A further advantage of this technique is the ability to vary the bandgap continuously and controllably.
