摘要

Nitrogen doped Indium oxide (In_2O_3) thin films have been investigated for their suitability as a potential sensor for the detection of ethanol vapour.With urea as a precursor, N-In_2O_3 thin films of various thicknesses have been synthesised by sol-gel technique.The response transients of the films have been found to follow Freundlich adsorption isotherm from the conductance transient analysis.The heat of adsorption (Q) and adsorption activation energy (Ea) have been estimated for the films.Further, ethanol sensing performance of the N-In_2O_3 films have been found to depend strongly on their microstructure.A significantly large sensing response (R_a/R_g～313 for 300 ppm ethanol) have been recorded for ～250 nm thick N-In_2O_3 film for which the heat of adsorption has been the highest.Two leading factors, namely the modification of surface electron distribution and effective surface areas, have been suggested to regulate the ethanol sensing properties of N-In_2O_3 thin films.
