我们报告说，完全端键合的多壁碳纳米管（MWNTs）可以表现出超导性的转变温度（T-c）高达12 K，这是大约30倍以上的T-c报告单壁纳米管绳。我们发现，这种超导电性的出现是高度敏感的Au电极/MWNTs的结结构。这表明，只有具有最佳数量的电激活壳层的MWNT，这是通过端键合实现的，可以允许由于壳层间效应的超导性。
We report that entirely end-bonded multiwalled carbon nanotubes (MWNTs) can exhibit superconductivity with a transition temperature (T-c) as high as 12 K, which is approximately 30 times greater than T-c reported for ropes of single-walled nanotubes. We find that the emergence of this superconductivity is highly sensitive to the junction structures of the Au electrode/MWNTs. This reveals that only MWNTs with optimal numbers of electrically activated shells, which are realized by end bonding, can allow superconductivity due to intershell effects.
