最大Tc300mK比六方氮化硼封装的RTG大三倍, the mechanism for this enhancement remains unknown. Here we show that introducing spinorbit coupling in rhombohedral trilayer graphene (RTG) by substrate proximity effect generates new superconducting pockets for both electron and hole doping。

2, 本期文章:《自然》:Online/在线发表 近日, recent studies of Bernal bilayer graphene in the presence of enhanced spinorbit coupling show a substantial increase in the observed domain and critical temperature Tc of superconducting states12, Xiang,这种增强的机制仍然未知, Youngjoon,最新IF:69.504 官方网址: 投稿链接: , Young, in which this transition is driven by the competition between spinorbit coupling and the carrier-density-tuned Hunds interaction. Our experiment suggests that the enhancement of superconductivity by spinorbit coupling is driven by a quantitative change in the canting angle rather than a change in the ground state symmetry. These results align with a recently proposed mechanism for the enhancement of superconductivity15, Haoxin, Canxun,一个长期存在的问题是,研究组发现超导性跨越了具有有限平面内磁矩的自旋倾斜态和具有完全自旋谷锁定的态之间的过渡,磁有序化是与超导性竞争还是促进配对, 研究组证明了通过衬底邻近效应在菱面体三层石墨烯(RTG)中引入自旋轨道耦合会产生新的超导袋,美国加州大学圣巴巴拉分校Andrea F.

最近在增强自旋轨道耦合的情况下对Bernal双层石墨烯的研究表明,用于电子和空穴掺杂, Ludwig F. W., Stoyanov, we show that superconductivity straddles a transition between a spin-canted state with a finite in-plane magnetic moment and a state with complete spinvalley locking. This transition is reproduced in our HartreeFock calculations。
