The paper presents Tin oxide (SnO2) based low cost, high temperature operable resistive type low humidity (10–20%RH) sensor. SnO2 thin films were prepared by spin coating 50 μl of synthesized (SnCl2) solution on alumina substrate (1.44 cm2). Material characterization of the synthesized material was carried out using UV-Visible, SEM and XRD. To get films of higher thickness they were coated from 1...
In this work, the annealing effects of e-beam deposited Ta2O5 films on the pH sensitivities of EIS based sensors are presented. XPS studies confirmed that the films annealed above 700 °C showed the best stoichiometry (Ta1.96O5.04) compared to the as deposited film and the films annealed till 600 °C. XRD spectra confirmed the amorphous nature of the as deposited film, which remained amorphous till...
Cadmium zinc oxide (CdXZn1−XO) thin films were deposited at low substrate temperature using advanced spray pyrolysis technique. Aqueous solution of cadmium acetate and zinc acetate were used as initial ingredients. The films were prepared by keeping optimized preparative parameters constant. Influence of variation of zinc in the ‘CdXZn1−XO’ system on the structural, electrical and gas sensing properties...
