High-density carrier doping by ionic liquids ; Application to Transition metal compounds

使用电子设备控制相变不仅从基本观点来看是令人兴奋的，而且还为传感器、信号转换器和存储器提供了潜在的应用。我们用离子液体电解液对栅介质层进行了高密度载流子掺杂，不仅成功地制作了高性能的有机场效应晶体管，而且还展示了过渡金属氧化物薄膜中金属-绝缘体转变的电场控制。

Using an electronic device to control phase transitions is not only exciting from fundamental view points, but also offers potential applications for sensors, signal converters and memories. We have performed high-density carrier doping by ionic liquid electrolytes used for gate dielectric layers and succeed to make not only high performance organic field-effect transistors but also demonstrate electric-field control of metal-insulator transition in transition metal oxide thin films.
