Electrodeposition and growth mechanism of SnSe thin films

▶ The electrodeposition of the SnSe thin films was studied using cyclic voltammetry, compositional, structural, optical measurements and surface morphology. ▶ The film growth proceeds via nucleation, growth of film layer and formation of needle-like particles on the overlayer of the film. ▶ The morphologies of SnSe thin films could be changed from spherical grains to platelet-like particles as the deposition potential increases.
