AB  - In this study we deposited new, ternary thin films of copper aluminum oxide with p-type and n-type behavior using RF magnetron sputtering for use as chemical gas sensors. p-Type materials are known to be good catalysts and can be combined with the well-known n-type materials for chemiresistive sensors application. Copper aluminum oxide in the delafossite phase CuAlO2 is a ternary oxide that has generated interest as a transparent p-type conducting material, while in the spinel phase CuAl2O4 is known to be n-type. We demonstrated that thin films of copper aluminum oxide with the proper resistance can be successfully applied as p-and n-type resistive gas sensors for ozone detection. We have studied the sputtering deposition conditions from a CuAlO2 sintered target by changing the substrate temperature in inert Ar atmosphere. In addition, post-deposition annealing in O-2 atmospheres was also tested. XRD, SEM and Raman investigations were used to characterize the thin films. Selected films with mixed phases of CuAlO2, CuAl2O4 and CuO were tested for gas sensing as resistive chemical sensors, showing promising results with ozone, acetone and ethanol.

AB  - An experimental approach for the detection of harmful gases in presence of humidity has been applied for gas sensors based on p-type Cu-Al-Oxide thin films. The impact of deposition conditions on the surface, morphology and sensing properties of the semiconducting oxide thin films are investigated. Cu-Al-Oxide thin film with higher resistance can be applied as p-type resistive gas sensor for the detection of pollutant gases. Thin films were characterized by X-Ray Diffraction, scanning electron microscope, and Raman spectroscopy. We observed that inert atmosphere and deposition temperature play the important role to affect the structural and surface morphology of Cu-Al-Oxide thin films. Sensitivity of nanostructured thin films towards reducing and oxidizing gas are studied as a function of gas concentration and operating temperature.
