Investigation was made on the interface characteristics between various metal electrodes and SrTiO3 single crystals at high-temperatures. The interfaces showed the non-linear current-voltage characteristics, which was caused by the Schottky barrier formed at the interface. The estimated Schottky barrier heights were approximately 1.5 eV, which were almost independent of the work function of electrode metal. These results indicated that the barrier formation obeys the diffusion mechanism for the Bardeen limit at high-temperature.
