Diameter dependent superconductivity in individual WS<sub>2</sub> nanotubes

ORAL

Abstract

Transition metal dichalcogenides nanotube is a fascinating platform for the research of superconductivity due to its unique dimensionality and geometry. Especially, novel chiral superconducting transport originating from the nanotube chirality has been discovered recently [F. Qin et al., Nature Commun. 8, 14465 (2017)]. Here we report the diameter dependent superconductivity in individual WS2 nanotubes. The superconductivity is realized by electrochemical doping with ionic gate, in which the diameter of nanotube is estimated from the periodic oscillating magnetoresistance, known as Little Parks effect. The critical temperature of superconductivity displays a systematic behavior as a function of the diameter. The present results might offer the crucial information to understand the microscopic mechanism of superconductivity in individual nanotube.
