Ultrafast Energy- and Momentum-resolved Surface Dirac Photocurrents in the Topological Insulator SbTe
Kenta Kuroda, J. Reimann, K. A. Kokh +4
We present energy-momentum mapping of surface Dirac photocurrent in the topological insulator SbTe by means of time- and angle-resolved two-photon photoemission spectroscop…
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…
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…
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…
Experimental realization of a topological p-n junction by intrinsic defect-grading
T. Bathon, S. Achilli, P. Sessi +4
A junction between an n- and p-type semiconductor results in the creation of a depletion region whose properties are at the basis of nowadays electronics. If realized using topolog…
