Achieving environmental stability in an atomically thin quantum spin Hall insulator via graphene intercalation

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-7 (2024)

Abstract Atomic monolayers on semiconductor surfaces represent an emerging class of functional quantum materials in the two-dimensional limit — ranging from superconductors and Mott insulators to ferroelectrics and quantum spin Hall insulators. Ind

Time-reversal symmetry breaking type-II Weyl state in YbMnBi2

Autor: Sergey Borisenko, Daniil Evtushinsky, Quinn Gibson, Alexander Yaresko, Klaus Koepernik, Timur Kim, Mazhar Ali, Jeroen van den Brink, Moritz Hoesch, Alexander Fedorov, Erik Haubold, Yevhen Kushnirenko, Ivan Soldatov, Rudolf Schäfer, Robert J. Cava

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-10 (2019)

Candidate materials containing magnetic Weyl fermions remain rare. Here, the authors report evidence of a magnetic Weyl state and observe the surface Fermi arcs in YbMnBi2.

Menshchikova, Viola Duppel, Daniel Friedrich, Richard Weihrich, Arno Pfitzner, Alexander Zeugner, Anna Isaeva, Setti Thirupathaiah, Yevhen Kushnirenko, Emile Rienks, Timur Kim, Evgueni V. Chulkov, Bernd Büchner, Sergey Borisenko

Publikováno v: APL Materials, Vol 7, Iss 12, Pp 121106-121106-7 (2019)

We report experimental and theoretical evidence that GaGeTe is a basic Z2 topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well as surface state electrons. This electronic situation is qualitatively si
