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…
Interface-induced collective phase transition in VO2-based bilayers studied by layer selective spectroscopy
D. Shiga, S. Inoue, T. Kanda +6
We investigated the origin of collective electronic phase transitions induced at the heterointerface between monoclinic insulating VO2 and rutile metallic electron-doped VO2 layers…
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…
Fermi Surface Reconstruction and Anisotropic Linear Magnetoresistance in the Charge Density Wave Topological Semimetal TaTe4
D. Silvera-Vega, J. Rojas-Castillo, E. Herrera-Vasco +7
Understanding the interplay between topology and correlated electron states is central to the study of quantum materials. TaTe is a quasi-one-dimensional charge density wave (C…
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…
