P-type cuprous oxide thin films electrodeposited on a titanium substrate in a lactate bath was investigated for liquid petroleum gas (LPG) sensing. Contact angle measurements using water droplets revealed that the surfaces ...

The surface of electrodeposited n-Cu2O thin films were modified by sulphidation using aqueous Na2S followed by (NH4)2S vapor treatment. Compared to untreated thin films, the resultant films showed an enhanced response ...
