Experimental observation of hidden Berry curvature in inversion-symmetric bulk 2H-WSe2
Soohyun Cho, Jin-Hong Park, Jisook Hong +11
We investigate the hidden Berry curvature in bulk 2H-WSe2 by utilizing the surface sensitivity of angle resolved photoemission (ARPES). The symmetry in the electronic structure of…
Realization of a Type-II Nodal-Line Semimetal in MgBi
Tay-Rong Chang, Ivo Pletikosic, Tai Kong +9
Nodal-line semimetals (NLSs) represent a new type of topological semimetallic beyond Weyl and Dirac semimetals in the sense that they host closed loops or open curves of band degen…
Temperature-Dependent Electron-Electron Interaction in Graphene on SrTiO3
Hyejin Ryu, Jinwoong Hwang, Debin Wang +6
The electron band structure of graphene on SrTiO3 substrate has been investigated as a function of temperature. The high-resolution angle-resolved photoemission study reveals that…
Observation of two-dimensional Fermi surface and Dirac dispersion in YbMnSb
Robert Kealhofer, Sooyoung Jang, Sinéad M. Griffin +9
We present the crystal structure, electronic structure, and transport properties of the material YbMnSb, a candidate system for the investigation of Dirac physics in the presen…
Nearly-free-electron system of monolayer Na on the surface of single-crystal HfSe
T. Eknapakul, I. Fongkaew, S. Siriroj +8
The electronic structure of a single Na monolayer on the surface of single-crystal HfSe is investigated using angle-resolved photoemission spectroscopy. We find that this syste…
Irreversible proliferation of magnetic moments at cleaved surfaces of the topological Kondo insulator SmB6
Haowei He, Lin Miao, Edwin Augustin +10
The compound SmB is the best established realization of a topological Kondo insulator, in which a topological insulator state is obtained through Kondo coherence. Recent studie…
