Nanosized titania thick and thin films were produced and shown to possess sensing capability. Correlation between electrical performance and structural features is inferred, with particular emphasis to the role played by the grain size. The nanostructured nature of the layers allows the films to be operated within a remarkably lower temperature range (350–800°C) with respect to previously existing titania bulk sensors. The films are sensitive to CO and NO2.

Abstract
Nanosized titania thick and thin films were produced and shown to possess sensing capability. Correlation between electrical performance and structural features is inferred, with particular emphasis to the role played by the grain size. The nanostructured nature of the layers allows the films to be operated within a remarkably lower temperature range (350–800°C) with respect to previously existing titania bulk sensors. The films are sensitive to CO and NO2.File in questo prodotto:
