Copper oxide thin films are deposited low pH (<6) and low and high temperatures (10°C and 60°C), using cathodic electrochemical deposition. The effects of the deposition current densities are studied in a range including values high enough to electrolyze water, promoting hydrogen bubbles generation. The influences of deposition variables on film composition and structural, morphological, and optical properties are investigated. Auger electron spectroscopy results indicate the fabrication of
