摘要:

低维曲边系统的研究是一个非常有意义的课题。这样的调查包括二维系统的圆柱对称。在这项工作中,我们提出了一个数值研究的电子输运性质的金属纳米管偏离圆柱形的形式,无论是有一个凸起或凹陷,并在磁场的影响下。在这些情况下,发现纳米管可以用作电子的能量高通滤波器。它还表明,该设备可以用来调整传输电子的角动量。

英文摘要:

The investigation of curved low-dimensional systems is a topic of great research interest. Such investigations include two-dimensional systems with cylindrical symmetry. In this work, we present a numerical study of the electronic transport properties of metallic nanotubes deviating from the cylindrical form either by having a bump or a depression, and under the influence of a magnetic field. Under these circumstances, it is found that the nanotube may be used as an energy high-pass filter for electrons. It is also shown that the device can be used to tune the angular momentum of transmitted electrons.
