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.

线性碳链中的超导性和具有几何角度的零偏峰的工程:一种新方法

我们通过产生线性碳链的共振峰,研究了滑角(在超导准一维碳结构中名为α的几何参数)的影响。我们还研究了状态密度以及不同滑移角对该结构的影响。我们发现滑移角的有趣作用类似于混合超导状态,在超导准一维碳结构的电子-空穴激发光谱中产生了类似质量的间隙。在Dirac-Bogoliubov-de Gennes形式主义的框架内,我们研究了超导线性碳链中的传输性质。超导体间隙被认为是自旋-小和自旋-三重态的超导状态。
