Potentiostatic deposition and characterization of Cu2O thin films

Semiconducting Cu2O thin films were electrodeposited potentiostatically on Cu and SnO2, substrates. The deposition kinetics of film growth and the conditions to obtain spotty and uniform Cu2O films are studied. X-ray diffraction studies revealed the formation of single phase cubic Cu2O films. The effects of deposition potential, solution pH and bath temperature on the structure are studied. The optical, electrical, composition and morphological analysis are carried out for Cu2O films prepared at various deposition conditions and the results are discussed.
