Title: High-Tc superconductivity in entirely end-bonded multi-walled carbon nanotubes
Author: Haruyama, J.; Kobayashi, N.; Takesue, I.; Chiasi, S.; Maruyama, S.; Sugai, T.; Shinohara, H.
Abstract: 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 T c as high as 12K that is approximately 50-times larger than those in ropes of single-walled nanotubes. We find that emergence of this superconductivity is very sensitive to junction structures of Au 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. This superconductive MWNT will lead to molecular quantum computation and teleportation systems.
