Dimensional control of the band-gap crossover in layered lead iodide
M. Rosmus, A. Antezak, A. Ptok +11
Before assessing the suitability of a semiconductor for specific applications, the first question to ask is whether it possesses a direct or indirect band gap. This distinction is…
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…
Electronic structure dimensionality of the quantum-critical ferromagnet YbNiP
J. Dai, A. Antezak, W. Broad +15
YbNiP is the first known ferromagnetic metal showing a second-order quantum phase transition. Current theoretical understanding rules out second order ferromagnetic quantum…
