摘要

我们已经开发了一种技术来测量碳纳米管在非常低的温度下的输运测量。碳纳米管通过低接触电阻与金属衬垫连接。如果正常电极之间的距离足够大，则可以观察到固定在正常触点上的单壁碳纳米管的固有超导性，否则超导性会被邻近效应破坏。这些实验表明，碳纳米管中存在吸引相互作用，在低温下克服了库仑排斥相互作用。

Intrinsic Superconductivity in Ropes of Carbon Nanotubes

We have developed a technique for measuring transport measurements on carbon nanotubes at very low temperature. Carbon nanotubes are connected through low contact resistance to metallic pads. It has been possible to observe intrinsic superconductivity in ropes of single wall carbon nanotubes mounted on normal contacts provided that the distance between the normal electrodes is large enough, otherwise superconductivity is destroyed by proximity effect. These experiments indicate the presence of attractive interactions in carbon nanotubes which overcome coulomb repulsive interactions at low temperature.
