手性金属单壁纳米管制备量子点

Quantum dot from chiral metallic single walled nanotubes

Riju Banerjee, Joydeep Bhattacharjee

摘要:

我们提出了一种简单的方法来构建一个量子点和它的电极使用手性金属单壁碳纳米管(CM-SWCNT)片段完全相反的手性$(m,n)$和$(n,m)$。电子约束的程度和能量关键取决于$n$和$m$的选择,以及构成量子点和电极的SWCNT片段的共线性。原则上,所有的链段都可以通过简单操作手性的单个纳米管的片段$(m,n)$或$(n,m)$来获得。

英文摘要:

We propose a simple approach to construct a quantum-dot and it's electrodes using chiral metallic single walled carbon nanotube (CM-SWCNT) segments of exactly opposite chiralities $(m,n)$ and $(n,m)$. The degree and energetics of electron confinement crucially depends on the choice of $n$ and $m$, and collinearity of the SWCNT segments constituting the quantum-dot and the electrodes. All the segments can in principle be obtained through simple manipulations of fragments of a single nanotube of chirality either $(m,n)$ or $(n,m)$.
