奇电子相互作用对单壁碳纳米管电子结构的影响

Electronic Structure of Single-Walled Carbon Nanotubes Governed by Odd-Electrons Interaction

Elena F. Sheka, Leonid A. Chernozatonskii

摘要:

首次提出了一种定量描述单壁碳纳米管电子结构的方法,并从管长和端部结构的角度预测了管控功能化的活性位点.该方法是基于与奇电子连接的管特性的功能,并说明了一个家庭,涉及片段的扶手椅配置(4,4)单壁纳米管的长度和端部结构不同。短和长管以及管帽端和开放端,在后一种情况下,氢终止和空的,被认为是。提出了任意长度圆管的定量描述算法。计算是在单行列式非限制性Hartree-Fock方法的框架内进行的。

英文摘要:

For the first time, an approach is suggested for the quantitative description of the electronic structure of single-walled carbon nanotubes and the prediction of active sites for the tube controlled functionalization in view of the tube length and ends structure. The approach is based on the tube characteristic feature connected with odd electrons and is illustrated for a family involving fragments of arm-chair configured (4,4) single-walled nanotubes differing by length and end structure. Short and long tubes as well as tubes with cap end and open end, in the latter case, both hydrogen terminated and empty, are considered. Algorithms of the quantitative description of the tubes of any length are suggested. Calculations were performed in the framework of the single-determinant unrestricted Hartree-Fock approach.
