Abstract

Interfacial microstructure tunable photovoltaic effects have been reported in heterojunctions of La1xCaxMnO3 thin films and tilted or exact cut Nb-doped SrTiO3 single crystal substrates under irradiation of UV pulsed laser. The photoresponse times of vicinal junctions and films were obviously faster than those of exact cut samples. The behaviors can be explained by the slope of the built-in electric field in the 10° tilted heterojunction and the interfacial terrace microstructure of La1xCaxMnO3 films.
