Experimental electronic structure of the mineral superconductor covellite CuS
Alexandre Antezak, Takemi Kato, Pedro Rezende Gonçalves +5
Covellite (CuS) is the first known natural mineral superconductor. Despite its simple chemical formula, covellite exhibits a rich crystal structure at the origin of several remarka…
Correlated Structural and Optical Characterization during Van der Waals Epitaxy of PbI2 on Graphene
C. P. Sonny Tsotezem, E. M. Staicu Casagrande, A. Momeni +11
Van der Waals heterostructures of 2D layered materials have gained much attention due to their flexible electronic properties, which make them promising candidates for energy, sens…
Metallic layered materials with magnetic frustration: An ARPES view of the SmAuAlGe and TbAuAlGe
P. Rezende-Gonçalves, A. Antezak, T. Kato +10
Compounds of the new materials class LnTAlX (Ln = lanthanide, X = tetrel, T = transition metal) host exotic magnetic phenomena due to geometric frustration induced by their…
ARPES studies of Hf(0001) surface: flat bands formation in the dice lattice
Laxman Nagireddy, Saleem Ayaz Khan, Maria Christine Richter +8
We present the first electronic structure measurements of the Hf(0001) single-crystal surface using angle-resolved photoemission spectroscopy (ARPES). The ARPES results are support…
Tunable Octdong and Spindle-Torus Fermi Surfaces in Kramers Nodal Line Metals
Gabriele Domaine, Moritz H. Hirschmann, Kirill Parshukov +9
It has recently been proposed that all achiral non-centrosymmetric crystals host so-called Kramers nodal lines, which are doubly degenerate band crossings connecting time-reversal…
Observation of the Dirac Dispersions in Co-doped CaFe2As2
Marcin Rosmus, Natalia Olszowska, Rafal Kurleto +2
We performed an angle-resolved photoemission spectroscopy (ARPES) study of the electronic structure of the CaFeAs 122-iron pnictide, a parent compound, and two iron-based s…
