A sample-position-autocorrection system with precision better than 1 \um~in angle-resolved photoemission experiments
Shaofeng Duan, Shichong Wang, Yuanyuan Yang +4
We present the development of a high-precision sample-position-autocorrection system for photoemission experiments. A binocular vision method based on image pattern matching calcul…
Unusual band splitting and superconducting gap evolution with sulfur substitution in FeSe
Yuanyuan Yang, Qisi Wang, Shaofeng Duan +7
High-resolution angle-resolved photoemission measurements were taken on FeSeS (x=0, 0.04, and 0.08) superconductors. With an ultrahigh energy resolution of 0.4 meV, unu…
Disorder-induced linear magnetoresistance in Sr-doped Bi2Se3 thin films
Jiayuan Hu, Wenxiang Jiang, Guohua Wang +8
Sr-doped Bi2Se3 thin films was known as a potential candidate of topological superconductor. The magnetoresistance (MR) of SrxBi2Se3 films with various doping concentrations x were…
Optical manipulation of electronic dimensionality in a quantum material
Shaofeng Duan, Yun Cheng, Wei Xia +9
Exotic phenomenon can be achieved in quantum materials by confining electronic states into two dimensions. For example, relativistic fermions are realised in a single layer of carb…
Achieving 50 femtosecond resolution in MeV ultrafast electron diffraction with a double bend achromat compressor
Fengfeng Qi, Zhuoran Ma, Lingrong Zhao +12
We propose and demonstrate a novel scheme to produce ultrashort and ultrastable MeV electron beam. In this scheme, the electron beam produced in a photocathode radio-frequency (rf)…
A time- and angle-resolved photoemission spectroscopy with probe photon energy up to 6.7 eV
Yuanyuan Yang, Tianwei Tang, Shaofeng Duan +3
We present the development of a time- and angle-resolved photoemission spectroscopy based on a Yb-based femtosecond laser and a hemispherical electron analyzer. The energy of the p…
