Taniguchi, 在传统超导体中, 实验结果与一个理论模型定性吻合, Codecido, unlike conventional superconductors, phonons or a combination of both. Here we show that,库珀对的形成由声子介导,创刊于2005年, the superconductivity in twisted bilayer graphene is strongly dependent on the dielectric environment. We place twisted bilayer graphene a short distance above a bulk SrTiO3 substrate that has a large and tunable dielectric constant. By raising the dielectric constant in situ in both magic-angle and large-angle devices。
we observe steady suppression and eventually a complete extinguishing of the entire superconducting dome. The experimental results are in qualitative agreement with a theoretical model in which the pairing mechanism arises from Coulomb interactions that are screened by plasmons, the formation of Cooper pairs is mediated by phonons. For the superconducting phases in moir materials, Pierre A., Marc W., Lau, 本期文章:《自然—物理学》:Online/在线发表 近日, Bockrath, Aatmaj。
