Robust spin-polarized midgap states at step edges of topological crystalline insulators
Paolo Sessi, Domenico Di Sante, Andrzej Szczerbakow +11
Topological crystalline insulators are materials in which the crystalline symmetry leads to topologically protected surface states with a chiral spin texture, rendering them potent…
Single electron gating of topological insulators
Paolo Sessi, Thomas Bathon, Konstantin A. Kokh +2
Introducing, observing, and manipulating individual impurities coupled to a host material offers the opportunity to create new device concepts based on single spin and charge state…
Mapping the effect of defect-induced strain disorder on the Dirac states of topological insulators
Oliver Storz, Alberto Cortijo, Stefan Wilfert +6
We provide a detailed microscopic characterization of the influence of defects-induced disorder onto the Dirac spectrum of three dimensional topological insulators. By spatially re…
Impurity screening and stability of Fermi arcs against Coulomband magnetic scattering in a Weyl monopnictide
Paolo Sessi, Yan Sun, Thomas Bathon +9
We present a quasiparticle interference study of clean and Mn surface-doped TaAs, a prototypical Weyl semimetal, to test the screening properties as well as the stability of Fermi…
Mesoscopic electron focusing in topological insulators
P. Sessi, P. Rüßmann, T. Bathon +15
The particle wave duality sets a fundamental correspondence between optics and quantum mechanics. Within this framework, the propagation of quasiparticles can give rise to superpos…
