摘要

本文研究了Al, Pd, Sc与碳纳米管(CNT)之间的端接触和侧接触结构。不同的结构显示了金属-碳纳米管接触界面上不同的化学键和电荷转移。提出了一种基于偶极子效应的肖特基势垒高度计算方法。不同的触点shs是由于金属原子的电负性和化学键的不同造成的。

Chemical Bonding and Schottky Barrier for Metal-Carbon Nanotube Contacts

We investigate both end-contact and side-contact structures between Al, Pd, Sc and carbon nanotube (CNT) in this paper. The different structures show the different chemical bonds and charge transfer at the metal-CNT contact interfaces. A novel method based on dipole effect is proposed to calculate the Schottky barrier height (SBH). Different SBHs for the contacts are due to different electro-negativity of metal atoms as well as the chemical bonds.
