Research Abstract |
With an aim of application utilizing strongly correlated electron materials, correlated heterojunctions with vanadium oxides were fabricated. Metal-insulator transition of the most prominent feature in vanadium dioxide emerges even at the heterointerface. It was found that work function of vanadium dioxide can be tuned with electron-or hole-doping. Furthermore, it has been demonstrated that the metal-insulator transition can be controlled by external fields such as electric field, light, and pressure.
