Abstract

Pulsed laser deposition (PLD) was used to create thin copper-doped cadmium oxide (CdO) films at various concentrations. The deposition process was done at room temperature (300 K). The surface morphology of the CdO thin films revealed an intricate network resembling a prism. The cubic crystal nanostructure and the CdO thin films are aligned in a (1 1 1) plane. At an operating temperature of 280 degrees Celsius, the sensing characteristics of CdO thin films with a carbon dioxide (CO) nanonanostructure were investigated. The results showed that increasing the copper concentration or increasing the gas concentration to 200 ppm would increase the sensitivity of the gas.
