Observation of tunneling gap in epitaxial ultrathin films of pyrite-type copper disulfide
Chong Liu, Haohao Yang, Can-Li Song +5
We report scanning tunneling microscopy investigation on epitaxial ultrathin films of pyrite-type copper disulfide. Layer by layer growth of CuS2 films with a preferential orientat…
Origin of charge transfer and enhanced electron-phonon coupling in single unit-cell FeSe films on SrTiO3
Huimin Zhang, Ding Zhang, Xiaowei Lu +7
Interface charge transfer and electron-phonon coupling have been suggested to play a crucial role in the recently discovered high-temperature superconductivity of single unit-cell…
An extensive impurity-scattering study on the pairing symmetry of monolayer FeSe films on SrTiO3
Chong Liu, Jiahao Mao, Hao Ding +10
Determination of the pairing symmetry in monolayer FeSe films on SrTiO3 is a requisite for understanding the high superconducting transition temperature in this system, which has a…
Experimental Observation of the Quantum Anomalous Hall Effect in a Magnetic Topological Insulator
Cui-Zu Chang, Jinsong Zhang, Xiao Feng +20
The quantized version of the anomalous Hall effect has been predicted to occur in magnetic topological insulators, but the experimental realization has been challenging. Here, we r…
Probing Dirac Fermion Dynamics in Topological Insulator BiSe Films with Scanning Tunneling Microscope
Can-Li Song, Lili Wang, Ke He +4
Scanning tunneling microscopy and spectroscopy have been used to investigate the femtosecond dynamics of Dirac fermions in the topological insulator BiSe ultrathin films. A…
Disentangling the magnetoelectric and thermoelectric transport in topological insulator thin films
Jinsong Zhang, Xiao Feng, Yong Xu +14
We report transport studies on (Bi,Sb)2Te3 topological insulator thin films with tunable electronic band structure. We find a doping and temperature regime in which the Hall coeffi…
