The measurements of the response-in terms of the conductance changes-to oxygen adsorption of tin dioxide (SnO₂) thin-film-based gas sensors were performed. The sensing SnO₂ layers were obtained by means of the rheotaxial growth and thermal oxidation (RGTO) method. The sensor responses were measured under a dry gas flow containing oxygen in nitrogen, within the range of temperature from 25 to 540 °C. For comparison, similar studies were performed for a commercial SnO₂ thick-film (TGS 812) gas sensor. The in-depth profiles of the chemical composition of the RGTO SnO₂ layers were determined from the scanning Auger microprobe experiment. The changes in concentration ratios [O]/[Sn] and [C]/[Sn] from the near-surface region towards the grain bulk were shown.
