摘要:

在石墨烯隔离技术的最新进展的刺激下,我们发现量子点可以被捕获在Z型石墨烯纳米结中。结的拓扑结构可以完全限制电子态。通过改变结的长度,我们可以改变结内的空间限制和离散能级的数量。此外,可以实现量子点,而不管衬底引起的静态无序或结的不规则边缘。该器件可用于方便地设计量子点器件。该平台还可用于设计使用石墨烯带的零维功能纳米级电子器件。

英文摘要:

Stimulated by recent advances in isolating graphene, we discovered that quantum dot can be trapped in Z-shaped graphene nanoribbon junciton. The topological structure of the junction can confine electronic states completely. By varying junction length, we can alter the spatial confinement and the number of discrete levels within the junction. In addition, quantum dot can be realized regardless of substrate induced static disorder or irregular edges of the junction. This device can be used to easily design quantum dot devices. This platform can also be used to design zero-dimensional functional nanoscale electronic devices using graphene ribbons.
