Abstract

The effect of thickness on the p.p.m. level H2 gas sensitivity of SnO2 nanoparticle-based thick film resistors is reported. The nanoparticles are synthesized by a sol-gel method and the films are prepared using standard screen printing technology. The thickness of the films is varied from a few micrometers to a few hundred micrometers. The results indicate that the sample having thickness 76 Μm gives the maximum sensitivity. The mechanism of the change in sensitivity with thickness is discussed.
