The first series was based on n-type semiconducting SnO(2) thin films, prepared by the sol gel method. The effect of Au and Pt nanoparticles in SnO(2) was investigated for gas sensor applications. The second series was based on p-type NiO thin films, which were grown by pulsed laser deposition on microscope glass or (100) Si substrates. The effect of substrate temperature and O(2) pressure during the deposition process on the morphological and sensing properties of the films has been investigated. The films were fully characterized. A significant response to a broad range of hydrogen concentrations was demonstrated for both series of films at operating temperatures lower than 200 degrees C. %> Αποθετήριο Ήλιος / ΕΙΕ
