APL007-2-4 Fabrication and Characterization of Nickel Cobaltite Nanostructures for Gas Sensing Applications
Abstract
In this work, nickel cobaltite nanostructures were prepared by dc reactive sputtering technique. The characterization measurements performed on the prepared films showed that the transmittance increases with the incident wavelengths, the polycrystalline structure contains of 5 crystallographic planes, the average particle size is about 25nm, the electrical conductivity is increasing linearly with increasing temperature, the activation energy is about 0.41 eV, and finally they showed high sensitivity to ethanol. This attempt is encouraging to fabricate nickel cobaltite nanostructures for some important applications.
