초록
In this work, highly uniform size-controlled Cu2O nanocubes can be successfully formed by means of pulse electrodeposition. The size distribution, crystal structure, and chemical state of deposited Cu2O nanocubes are characterized using scanning electron microscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The phase transition from Cu2O to Cu can be controlled by constant current electrodeposition as a function of deposition time. In particular, the size of the Cu2O nanocubes can be controlled using pulse electrodeposition as a function of applied current density.
