In this report we presented results of gas sensitivity' kinetics analysis for undoped SnO2 thin films, deposited by spray pyrolysis method, using SnCl4x5H2O alcohol solution. The comparison of gas sensitivity's kinetics in measurement cycles air→{air+(0.08-1.7%)CO}→air and air→{N2+0.5%O2}→air for different thickness of SnO2 films (d = 40-200 nm) and operating temperature (T = 150-400 °C) was carried out. We have determined the kinetic parameters (τ and Eact) and made a conclusion that kinetics of gas sensitivity is limited by the rate of SnO2 surface refilling by oxygen. |
