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…
Dual nature of magnetic dopants and competing trends in topological insulators
Paolo Sessi, Rudro Biswas, Thomas Bathon +8
Topological insulators interacting with magnetic impurities have been reported to host several unconventional effects. These phenomena are described within the framework of gapping…
