Abstract
Work function is known to be one of the parameters whose variation is induced by sensing effects. This is exploited by many basic devices, such as ChemFet and LAPS, to fabricate chemical sensors. On the other side Kelvin Probe is a well assessed experimental technique for direct measurement of work function. In this paper a new designed Kelvin Probe has been utilized to monitor the work function variation occurring in metalloporphyrins when they are exposed to volatile compounds. The results show that this technique is promising to fabricate new generation of chemical sensors on the direct monitoring of work function.
