Spectroscopic Evidence of Superconductivity Pairing at 83 K in Single-Layer FeSe/SrTiO3 Films.
Yu Xu,Hongtao Rong,Qingyan Wang,Dingsong Wu,Yong Hu,Yongqing Cai,Qiang Gao,Hongtao Yan,Cong Li,Chaohui Yin,Hao Chen,Jianwei Huang,Z. G. Zhu,Yuan Huang,Guodong Liu,Zuyan Xu,Lin Zhao,Xingjiang Zhou +17 more
TL;DR: Spectroscopic evidence of superconductivity pairing at 83 K in single-layer FeSe/STO films provides a new definitive benchmark of super conductivity pairing that is directly observed up to 83 K and finds that the pairing state can be further divided into two temperature regions.
