摘要

研究了在任意强度的纵向磁场作用下，电子通过引入纳米管的薄杂质势垒的多通道量子隧穿。详细研究了该系统的隧穿和极化特性，并说明了其与电子能量、纳米管半径和磁场感应强度的关系。结果表明，在一定的电子能量范围内，该系统可以作为电子流的理想偏振器。

Spin-Dependent Multichannel Tunneling of an Electron in a Nanotube with an Impurity in a Longitudinal Magnetic Field

Multichannel quantum tunneling of an electron through a potential barrier of a thin impurity introduced into a nanotube in the presence of a longitudinal magnetic field of arbitrary intensity is investigated. Tunneling and polarization characteristics of the system are studied in detail and illustrated as a function of the electron energy, nanotube radius, and magnetic field induction. It is indicated that in some electron energy ranges the system can operate as an ideal polarizer of the electron flow.
