Title

STUDY OF ELECTRICAL AND GAS SENSING PROPERTIES OF THERMALLY EVAPORATED NICKEL OXIDE THIN FILMS

Abstract

Thin films currently play an important role in the field of gas sensors. Thin films are changing the physical, electrical, structural, and gas sensing properties of the functional material. The current study explicates on the fabrication of NiO thin films by using thermal evaporation method and investigates their electrical and gas sensing properties. The films were fabricated on glass substrate. After fabrication, in a muffle furnace the films were annealed for 3 hours at 400°C. Resistivity, temperature coefficient ratio (TCR), and activation energy were used to investigate the electrical properties of fabricated NiO thin films. Gas sensing studies were carried out in the presence of NH3, LPG, NO2, and methanol in the surroundings of NiO thin films at various surrounding temperatures. The characteristics of sensitivity, selectivity, and response and recovery time were investigated. The maximum sensitivity was found to be NO2 gas. The sensitivity was 82.65% at 100 oC to NO2 gas of concentration 200 PPM. The response and recovery time were found to be ~ 05 sec and ~ 13 sec respectively.

Key Words

NiO, Thin films,NO2, selectivity and reproducibility.
