Printed semiconducting gas sensors

V. Guidi, C. Malagù, M.C. Carotta and B. Vendemiati,     University of Ferrara, Italy

Dedication: In memory of Professor Giuliano Martinelli – a wonderful person and an eminent scientist.

Abstract

Most common metal-oxide semiconductors featuring chemo-resistive effect, such as SnO2, TiO2, WO3 and ZnO, have been examined as functional materials for gas sensors via thick-film technology. Analysis of the mainly accepted electrical transport models through polycrystalline semiconductors has been carried out and compared to experimental evidence. A theoretical conduction model able to determine the characteristic length below which a material can be properly considered as nanostructured has been considered ...
