Epitaxial heterostructures constructed from the thermoelectric cobalt Bi2Sr2Co2Oy thin films and SrTiO3 as well as SrTi0.993Nb0.007O3 substrates were fabricated by pulsed-laser deposition. The scanning transmission electron microscopy results confirm that the heterostructures are epitaxial, with sharp and coherent interfaces. The temperature-dependent electrical transport properties and the Hall effects were systematically investigated. The Bi2Sr2Co2Oy/SrTi0.993Nb0.007O3 p-n heterostructure exhibits good rectifying current-voltage characteristics over a wide temperature range. A strong photovoltaic effect was observed in the Bi2Sr2Co2Oy/SrTi0.993Nb0.007O3 heterostructure, with the temperature-dependent photovoltage being systematically investigated. The present work shows a great potential of this new heterostructures as photoelectric devices. Copyright (C) EPLA, 2013
