Identifying the fingerprints of topological states by tuning magnetoresistance in a semimetal: the case of topological half-Heusler Pt1-xAuxLuSb
Shouvik Chatterjee, Felipe Crasto de Lima, John A. Logan +18
Topological materials often exhibit remarkably linear, non-saturating magnetoresistance (LMR), which is both of scientific and technological importance. However, the role of topolo…
Emergent quasiparticles in Euclidean tilings
F. Crasto de Lima, A. Fazzio
Material's geometrical structure is a fundamental part of their properties. The honeycomb geometry of graphene is responsible for the arising of its Dirac cone, while the kagome an…
Natural radioactive environments as sources of local disequilibrium for the emergence of life
Thiago Altair, Larissa M. Sartori, Fabio Rodrigues +2
Certain subterranean environments of Earth have naturally accumulated long-lived radionuclides, such as 238U, 232Th and 40K, near the presence of liquid water. In these natural rad…
Manipulation of Spin Transport in Graphene/Transition Metal Dichalcogenide Heterobilayers upon Twisting
Armando Pezo, Zeila Zanolli, Nils Wittemeier +4
Proximity effects are one of the pillars of exotic phenomena and technological applications of two dimensional materials. However, the interactions nature depends strongly on the m…
Jacutingaite-family: a class of topological materials
F. Crasto de Lima, R. H. Miwa, A. Fazzio
Jacutingate, a recently discovered Brazilian naturally occurring mineral, has shown to be the first experimental realization of the Kane-Mele topological model. In this letter we h…
Structural and electronic properties of realistic two-dimensional amorphous topological insulators
Bruno Focassio, Gabriel R. Schleder, Marcio Costa +2
We investigate the structure and electronic spectra properties of two-dimensional amorphous bismuthene structures and show that these systems are topological insulators. We employ…
Disorder effects of vacancies on the electronic transport properties of realistic topological insulators nanoribbons: the case of bismuthene
Armando Pezo, Bruno Focassio, Gabriel R. Schleder +3
The robustness of topological materials against disorder and defects is presumed but has not been demonstrated explicitly in realistic systems. In this work, we use state-of-the-ar…
The effect of structural and magnetic disorder on the 3-5 exchange interactions of LaCaCoIrO
L. Bufaiçal, E. Sadrollahi, F. J. Litterst +7
The delicate balance between spin-orbit coupling, Coulomb repulsion and crystalline electric field interactions observed in Ir-based oxides is usually manifested as exotic magnetic…
Simulation of XANES spectroscopy and the calculation of total energies for N-heterocyclic carbenes on Au(111)
Felipe Crasto de Lima, Adalberto Fazzio, Alastair B. McLean +1
It has recently been demonstrated that N-heterocyclic carbenes (NHCs) form self-assembled monolayers (SAMs) on metal surfaces. Consequently, it is important to both characterize an…
Phonon Scattering Mechanism in Thermoelectric Materials Revised via Resonant X-ray Dynamical Diffraction
Adriana Valério, Rafaela F. S. Penacchio, Maurício B. Estradiote +7
Engineering of thermoelectric materials requires an understanding of thermal conduction by lattice and electronic degrees of freedom. Filled skutterudites denote a large family of…
Dual Topological Insulator Device with Disorder Robustness
Bruno Focassio, Gabriel R. Schleder, Armando Pezo +2
Two-dimensional NaBi is a dual topological insulator protected by time-reversal and mirror symmetry, resulting in a promising platform for devices design. However, in reality,…
Discovery of Higher-Order Topological Insulators using the Spin Hall Conductivity as a Topology Signature
Marcio Costa, Gabriel R. Schleder, Carlos Mera Acosta +4
The discovery and realization of topological insulators, a phase of matter which hosts metallic boundary states when the -dimension insulating bulk is confined to ()-dimens…
Hot Hydride Superconductivity above 550 K
A. D. Grockowiak, M. Ahart, T. Helm +9
The search for room temperature superconductivity has accelerated dramatically in the last few years driven largely by theoretical predictions that first indicated alloying dense h…
Pressure tuning of the anomalous Hall effect in the chiral antiferromagnet Mn3Ge
R. D. dos Reis, M. Ghorbani Zavareh, M. O. Ajeesh +9
We report on the pressure evolution of the giant anomalous Hall effect (AHE) in the chiral antiferromagnet MnGe. The AHE originating from the non-vanishing Berry curvature in M…
Composition, Size, and Surface Functionalization dependent Optical Properties of Lead Bromide Perovskite Nanocrystals
Palvasha Ijaz, Muhammad Imran, Márcio M. Soares +6
The photoluminescence (PL), color purity, and stability of lead halide perovskite nanocrystals depend critically on the surface passivation. We present a study on the temperature d…
The Rashba Scale: Emergence of Band Anti-Crossing as a Design Principle for Materials with Large Rashba coefficient
Carlos Mera Acosta, Elton Ogoshi, Adalberto Fazzio +2
The spin-orbit -induced spin splitting of energy bands in low symmetry compounds (the Rashba Effect) has a long-standing relevance to spintronic applications and to the fundamental…
