Abstract

Three oxide heterojunctions made of BaTi O3-δ Si have been fabricated under various oxygen pressures by laser molecular beam epitaxy. They all exhibited nonlinear and rectifying I-V characteristics but with a large difference in the rectification behaviors. Their photoelectric properties and dependences on oxygen contents in BaTi O3-δ films have been experimentally studied. We found that the photovoltaic effects depended strongly on the oxygen contents of the BaTi O3-δ films. The possible mechanism was proposed based on the band structure of the p-n heterojunctions.
