Abstract

This work mainly focuses on the growth and chemical sensing nature of CuO thin films for organophosphate pesticide detection. Cu films were first grown on p-type silicon substrate [(100), 1–10 Ω cm] using RF magnetron sputtering at 50 W power and 4 × 10−3 mbar pressure. Thermal oxidation of the films was carried out in air atmosphere at temperatures varying from 200 to 800 °C. The structural investigations were carried out by X-ray diffraction (XRD) technique. A mixed phase of CuO and Cu2O was observed for the oxidation temperature of 200 °C. The FESEM micrographs have shown a uniform granular surface pattern at the oxidation temperature of 600 °C without any appearance of cracks. In order to study the sensing behavior, current–voltage measurements were carried out in an isolated sensing chamber at room temperature. A considerable increase in current was observed for the oxidized films in presence of organophosphate pesticide.
