CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishPolybithiophene (pbT) thin films have been electrochemically deposited on n-TiO2 prepared by electrochemical oxidation of titanium. The rectifying behaviour of this novel inorganic semiconductor/conducting polymer interface is demonstrated by cyclic voltammetry experiments, interpreted in the framework of Gerischer's theory on 'semiconductor/redox-electrolyte' interfaces treated as Schottky barriers. Moreover, experimental evidence of a photovoltaic effect is given by a photoelectrochemical investigation carried out by illuminating the pbT layer with photons of appropriate frequency.
