Induced superconductivity in linear carbon chains and engineering of zero-bias peaks with geometric angles: a new approach

Abstract

Abstract We investigated the effect of slip angle, a geometric parameter named as α in superconducting quasi-one-dimensional carbon structures, by engendering resonant peak of linear carbon chains. We studied also the density of states and the effect of different slip angles on this structure. We found the interesting role of the slip angle, similar to the mixed superconducting state, creating a mass-like gap in the electron-hole excitation spectrum of the superconducting quasi-one-dimensional carbon structure. In the framework of the Dirac-Bogoliubov–de Gennes formalism, we investigated the transport properties in the superconducting linear carbon chain. The superconductor gap is taken to be a spin-singlet and spin-triplet superconducting state.
