中文简介: | 我们结合基于非平衡格林函数形式的ab initio密度泛函和量子输运计算来比较Mo6S6 xIx纳米线与碳纳米管的结构,电子和传输特性。我们发现x = 2的系统特别稳定和刚性,其电子结构和电导率接近于金属(13,13)单壁碳纳米管的电子结构和电导。 Mo6S6 xIx纳米线无论其结构如何都是导电的,比碳纳米管更容易分离,并且能够通过硫基与Au引线形成理想的接触。 |
课程简介: | We combine ab initio density functional and quantum transport calculations based on the nonequilibrium Green’s function formalism to compare structural, electronic, and transport properties of Mo6S6-xIx nanowires with carbon nanotubes. We find systems with x=2 to be particularly stable and rigid, with their electronic structure and conductance close to that of metallic (13,13) single-wall carbon nanotubes. Mo6S6-xIx nanowires are conductive irrespective of their structure, more easily separable than carbon nanotubes, and capable of forming ideal contact to Au leads through thio groups. |
