Abstract

The structural, electrical and gas sensing properties of $LaFeO_3$ thick films with different heat treatments were examined. As the heat treatment temperature increases, the intensity of dominant(121) phase increases in XRD measurements. Activation energy changes with the heat treatment and sensitivity is high for the samples with high activation energy, $LaFeO_3$ films showed high sensitivity to NO, $NH_3$ and $C_{4}H_{10}$ gases.
