Observation of giant spin-split Fermi-arc with maximal Chern number in the chiral topological semimetal PtGa
Mengyu Yao, Kaustuv Manna, Qun Yang +14
Non-symmorphic chiral topological crystals host exotic multifold fermions, and their associated Fermi arcs helically wrap around and expand throughout the Brillouin zone between th…

Possible Experimental Realization of a Basic Z2 Topological Semimetal
Erik Haubold, Alexander Fedorov, Igor P. Rusinov +15
We report experimental and theoretical evidence that GaGeTe is a basic topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well…

Narrow photoluminescence peak of epitaxial MoS on graphene/Ir(111)
Niels Ehlen, Joshua Hall, Boris V. Senkovskiy +10
We report on the observation of photoluminescence (PL) with a narrow 18 meV peak width from molecular beam epitaxy grown MoS on graphene/Ir(111). This observation is explained…
