变形纳米管电子输运中的几何效应

Geometric effects in the electronic transport of deformed nanotubes

Fernando Santos, Sébastien Fumeron, Bertrand Berche, Fernando Moraes

摘要:

准二维系统可能存在曲率,这给它们的内部性质增加了三维影响。如da Costa \cite{dacosta}所示,在曲面上运动的带电粒子经历曲率依赖的电势,这极大地影响它们的动力学。本文研究了变形纳米管中的电子弹道输运。单电子薛定谔方程与开放的边界条件数值求解与灵活的MAPLE代码作为补充数据。我们发现,弯曲的变形确实有强烈的影响,电子动力学,建议其使用在基于纳米管的电子器件的设计。

英文摘要:

Quasi-two-dimensional systems may exibit curvature, which adds three-dimensional influence to their internal properties. As shown by da Costa \cite{dacosta}, charged particles moving on a curved surface experience a curvature-dependent potential which greatly influence their dynamics. In this paper, we study the electronic ballistic transport in deformed nanotubes. The one-electron Schrödinger equation with open boundary conditions is solved numerically with a flexible MAPLE code made available as Supplementary Data. We find that the curvature of the deformations have indeed strong effects on the electron dynamics suggesting its use in the design of nanotube-based electronic devices.
