TL;DR: In this article, the spin and angle-resolved photo-emission spectroscopy of spin-polarized bulk states in the centrosymmetric transition-metal dichalcogenide WSe has been used to show how spin splittings up to ∼ 0.5 eV result, with a spin texture that is strongly modulated in both real and momentum space.
Journal ArticleDOI
Weyl-like points from band inversions of spin-polarised surface states in NbGeSb
Igor Marković,Igor Marković,Chris Hooley,O. J. Clark,Federico Mazzola,Matthew D. Watson,J. M. Riley,K Volckaert,Kaycee Underwood,Matthew S. Dyer,Philip A. E. Murgatroyd,Keith Murphy,P. Le Fèvre,François Bertran,Jun Fujii,Ivana Vobornik,Shilong Wu,Taichi Okuda,Jonathan Alaria,Philip D. C. King +19 more
TL;DR: In this paper, a band inversion between manifolds of surface states is proposed to stabilize topological and symmetry-protected states in solids, by aliovalent substitution of Nb for Zr and Sb for S in the ZrSiS family of nonsymmorphic semimetals.
Journal ArticleDOI
Electronic Structure and Enhanced Charge-Density Wave Order of Monolayer VSe2
Jiagui Feng,Deepnarayan Biswas,Akhil Rajan,Matthew D. Watson,Federico Mazzola,O. J. Clark,Kaycee Underwood,Igor Marković,Igor Marković,Martin McLaren,Andrew Hunter,D. M. Burn,L. B. Duffy,L. B. Duffy,Sourabh Barua,Geetha Balakrishnan,François Bertran,Patrick Le Fèvre,Timur K. Kim,Gerrit van der Laan,Thorsten Hesjedal,Peter Wahl,Phil D. C. King +22 more
TL;DR: This study uses angle-resolved photoemission to investigate the electronic structure of monolayer VSe2 grown on bilayer graphene/SiC and shows that pronounced energy gaps develop over the entire Fermi surface with decreasing temperature below Tc = 140 ± 5 K, concomitant with the emergence of charge-order superstructures evident in low-energy electron diffraction.
Journal ArticleDOI
Oxygen switching of the epitaxial graphene-metal interaction.

TL;DR: These findings demonstrate that oxygen intercalation is an efficient method for fully decoupling an extended layer of graphene from a metal substrate, such as Ir(111), and pave the way for the fundamental research on graphene.
Journal ArticleDOI

TL;DR: In this paper, the authors focus on the transition metal dichalcogenides (TMDs) and find that these generically host a co-existence of type-I and type-II three-dimensional bulk Dirac fermions as well as ladders of topological surface states and surface resonances.
