The electromechanical behavior of single-walled carbon nanotubes (SWNTs) in contact with different materials is investigated by scanning probe microscopy. An anomalous diamond/semiconducting nanotube behavior is observed, which is consistent with ab initio calculations: the formation of a broken-gap heterojunction between semiconducting SWNTs and a hydrogenated diamond surface results in a metallic response for such SWNTs.
通过扫描探针显微镜研究了单壁碳纳米管（SWNTs）与不同材料接触时的机电行为。观察到异常的金刚石/半导体纳米管行为，与从头算计算一致：半导体 SWNTs 和氢化金刚石表面之间形成带隙中断的异质结，导致此类 SWNTs 呈现金属响应。
