Vortex lattice and vortex bound states in CsFeAs investigated by scanning tunneling microscopy/spectroscopy
Xiong Yang, Zengyi Du, Hai Lin +4
We investigate the vortex lattice and vortex bound states in CsFeAs single crystals by scanning tunneling microscopy/spectroscopy (STM/STS) under various magnetic fields. A…
Strong coupling superconductivity revealed by scanning tunneling microscope in tetragonal FeS
Xiong Yang, Zengyi Du, Guan Du +6
We investigate the electronic properties of the tetragonal FeS superconductor by using scanning tunneling microscope/spectroscopy. It is found that the typical tunneling spectrum o…
Drive the Dirac Electrons into Cooper Pairs in SrxBi2Se3
Guan Du, Jifeng Shao, Xiong Yang +9
Topological superconductor is a very interesting and frontier topic in condensed matter physics1. Despite the tremendous efforts in exploring the topological superconductivity, its…
Possible superconducting fluctuation and pseudogap state above in CsFeAs
Huan Yang, Jie Xing, Zengyi Du +5
Resistive, magnetization, torque, specific heat and scanning tunneling microscopy measurements are carried out on the hole heavily doped CsFeAs single crystals. A character…
