Abstract :
In this work the case of spherical grains will be discussed in order to point out that the reduction of the sensing film grain size changes the behavior, not always giving a better performance in terms of sensitivity, with respect to large grained films. The model was focused on p-type materials and some simulation results for YCoO3 are shown and discussed.
