Abstract

Epitaxial heterostructures constructed from the thermoelectric cobalt Bi₂Sr₂Co₂O_y thin films and SrTiO₃ as well as SrTi_0.993Nb_0.007O₃ 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 Bi₂Sr₂Co₂O _y/SrTi_0.993Nb_0.007O₃ p-n heterostructure exhibits good rectifying current-voltage characteristics over a wide temperature range. A strong photovoltaic effect was observed in the Bi ₂Sr₂Co₂O_y/SrTi _0.993Nb_0.007O₃ heterostructure, with the temperature-dependent photovoltage being systematically investigated. The present work shows a great potential of this new heterostructures as photoelectric devices.
