Description: 
An approach to the production of a new class of gas sensors consisting of nanostructured hybrid organic-inorganic thin films is proposed. It is based on the co-deposition from supersonic beams of π-conjugated organic materials and cluster-assembled metal oxides in a UHV apparatus including surface characterization methods. The unique control achievable by supersonic beams on the initial kinetic energy, momentum and state of aggregation enables the growth (SuMBE) of molecular materials with controlled properties at different length scales. On the other hand, by means of supersonic beams of clusters, nanocrystalline TiO2 films can be grown without annealing, so that grain size and morphology can be better controlled. We show that by the co-deposition of organic molecules and titania clusters, gas sensors based on sensitized nanostructured titania can be prepared exhibiting improved and novel gas …
