2M相WS2是新发现的一类亚稳相材料,在TMD材料中它具有最高的超导转变温度,Tc=8.9 K。隧道扫描电子谱观测到其具有U型超导能隙,在磁涡旋中可能存在马约拉纳边缘态。理论计算表明:与Fe基超导体类似,2M-WS2的Femi面附近也是电子和空穴共存。并且,2M-WS2存在...
基于薄层2M-WS2中的二维超导,课题组利用WM5的输运测量系统研究了薄层2M-WS2在低温强磁场下,面内上临界磁场的行为和超导能隙的演化。研究发现在超导转变温度以下,薄层2M-WS2 的面内上临界磁场大大超出了泡利极限,且呈现出很强的二重简并各向异...

we observe a U-shaped superconducting gap in 2M-WS2. Probable Majorana bound states are observed in magnetic vortices, which manifest as a non-split zero-energy state coexisting with the ordinary Caroli–de Gennes–Matricon bound states. Such non-split bound states in 2M-WS2show highly spatial...
