Superconductivity in entirely end-bonded multi-wailed carbon Superconductivity in entirely end-bonded multi-wailed carbon

摘要

We report that entirely end-bonded multi-walled carbon nanotubes (MWNTs) within Tomonaga-Luttinger liquid (TLL) states at high temperatures can show superconductivity with the transition temperature Tt as high as 12K that is approximately 40-times larger than those in ropes of single-walled nanotubes. We find that emergence of this superconductivity is very sensitive to junction structures of An electrode/MWNTs. This indicates that MWNTs with optimal numbers of electrically activated shells can allow the superconductivity that overcomes the TLL sates, due to intershell effects.
