摘要：

Cuprous oxide (Cu2O) thin films were deposited on indium tin oxide (ITO) coated glass by electrochemical deposition at different electrolyte temperature. The electrodeposition process was found to be a reductive irreversible process with a major phase, Cu2O, and appreciable amount of CuO. With the increasing temperature, the microstructure varied from fine grains, amorphous-like, to coarse pyramids, well-crystallized, which were identified as the texture development transforming from (200) to (111). Not only was the increasing temperature of electrodepostion found to induce the optical red-shift of band gap from 2.19 to 2.68 eV but it inhabited electrical transmittance with resistivity from 11.28 to 0.24 Omega-cm.
