Realization Of High-Temperature Superconductivity In Carbon-Nanotubes And Its Low Power Applications
Abstract
High transition temperature superconductivity gives significant impact to communities and people. I have previously studied SC in carbon nanotubes and attained the following results: (1) SC in array of entirely end-bonded multi-walled CNTs (MWNTs) with the world-higest transition temperature of 12 K. and (2) SC in thin films consisting of boron-doped single walled CNTs also with Tc of 12 Kelvin. I have found a possibility of a much higher Tc ~38K in CNT thin films with ionic-gel gate. Because CNTs are famous nano materials attracting significant attention, the high-Tc SCs in CNTs are highly important. Theories have predicted a potentially much higher Tc as high as ~64 Kelvin based on some unique electronic properties of CNTs, while no one has experimentally reported this to date. My group has the largest possibility fr such high Tc based on our previous results. In the present proposal, my challenge is to realize the high-Tc mainly by applying ionic liquid gating to thin films consisting of aligned extremely thin CNTs with diameter as small as 0.5 nm. The SC-CNTs have applications to low power applications (e.g. superconducting light weight wires, panels, and cables for aircrafts and aerospace systems).
