Abstract
The interaction of chemical species with molecular films of porphyrins caus es variations of the work function of the film itself, as it has been recen tly demonstrated by using the Kelvin probe technique. This characteristic m akes porphyrins films suitable to be used as sensitive layers in ChemFET se nsors. In this paper, we present a preliminary report about the fabrication and testing of such gas sensitive devices. The technological solutions tow ards an optimised device are also illustrated and discussed. (C) 2001 Elsev ier Science B.V. All rights reserved.
