摘要:

具有由准金属碳纳米管(CNT)形成的导电通道的三端器件被示出为在强磁场下作为基于纳米管的场效应晶体管操作。器件的关态电导随磁通量强度呈指数变化。我们提取的准金属CNT的手性以及肖特基势垒形成的金属纳米管接触的温度依赖性的磁导测量的特性。

英文摘要:

Three-terminal devices with conduction channels formed by quasi-metallic carbon nanotubes (CNT) are shown to operate as nanotube-based field-effect transistors under strong magnetic fields. The off-state conductance of the devices varies exponentially with the magnetic flux intensity. We extract the quasi-metallic CNT chirality as well as the characteristics of the Schottky barriers formed at the metal-nanotube contacts from temperature-dependent magnetoconductance measurements.
