Abstract

Porous alumina thin film has been investigated in order to find its sensitivity in the trace moisture level. Alumina, with two different phases were obtained using sol-gel process and fired between 400 degrees C to 1000 degrees C. FESEM, BET, AFM and XRD techniques were employed for microstructural characterization of the sintered thin film in two phases. A detailed analysis is done to assess the superiority of gamma (gamma) - over alpha (alpha) phase using impedance spectroscopy. It was observed that gamma phase is more sensitive towards trace level moisture sensing.
