Structural and Compositional Characterization of Mixed CdS ‐ CdSe Films Grown by Cathodic Electrodeposition

Abstract

Mixed films have been electrodeposited cathodically from DMSO solutions containing cadmium chloride, elemental sulfur and elemental selenium. The mixed films were characterized structurally using x‐ray diffraction, scanning electron microscopy, and Rutherford backscattering spectrometry. The photoelectrochemical response of the material was studied in a photoelectrochemical cell with a sulfide‐polysulfide electrolyte. It has been found that the composition and optical bandgap of the films can be varied by changing the composition of the deposition solution. However, the films with higher content are amorphous, and have a higher resistivity than pure .
