Thermally evaporated mgo-nio nanocomposite thin films for ethanol gas sensor
In the current research work, MgO-NiO nano composite thin films have been prepared on glass substrate by using thermal evaporation technique and studied electrical and gas sensing properties of prepared films. The prepared films were annealed for 2 hours at 350°C in a muffle furnace. The electrical properties of prepared MgO-NiO nano composite thin films were investigated on the basis of resistivity, Temperature Coefficient Resistance (TCR) and activation energy.
