## Abstract CdSe nanoparticles were electrodeposited on mechanically strained gold, the latter achieved by controlled bending of gold films evaporated on mica. It is shown that the size and bandgap of the electrodeposited CdSe quantum dots (QDs) can be varied by applying mechanical strain to the Au
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 th
