Abstract
Surface potential measurements for improving GASFET. The main criteria of gas sensor devices are the sensitivity and the selectivity towards the gas to be detected. A way to improve these properties is the surf ace modification by species able to catalyze the gas/solid interaction s. The influence of the deposition of Pd nanoparticles on the behavior of SnO2 structures in contact with various gases (H-2, CO) has been i nvestigated by using both surface potential and conductance measuremen ts.
