Probing spin-dependent charge transport at single-nanometer length scales
Patrick Härtl, Markus Leisegang, Jens Kügel +1
The coherent transport of charge and spin is one key requirement of future devices for quantum computing and communication. Scattering at defects or impurities may seriously reduce…
Anisotropic Ballistic Transport Revealed by Molecular Nanoprobe Experiments
Markus Leisegang, Robert Schindhelm, Jens Kügel +1
Atomic-scale charge transport properties are not only of significant fundamental interest but also highly relevant for numerous technical applications. However, experimental method…
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…
Signatures of Dirac fermion-mediated magnetic order
Paolo Sessi, Felix Reis, Thomas Bathon +3
The spin-momentum locking of topological states offers an ideal platform to explore novel magneto-electric effects. These intimately depend on the ability to manipulate the spin te…
