Long-lived non-equilibrium superconductivity in a non-centrosymmetric Rashba semiconductor
V. Narayan, P. C. Verpoort, J. R. A. Dann +8
We report non-equilibrium magnetodynamics in the Rashba-superconductor GeTe, which lacks inversion symmetry in the bulk. We find that at low temperature the system exhibits a non-e…
Thickness dependence of electron-electron interactions in topological p-n junctions
Dirk Backes, Danhong Huang, Rhodri Mansell +7
Electron-electron interactions in topological p-n junctions consisting of vertically stacked topological insulators are investigated. n-type Bi2Te3 and p-type Sb2Te3 of varying rel…
Infrared/Terahertz Spectra of the Photogalvanic Effect in (Bi,Sb)Te based Three Dimensional Topological Insulators
H. Plank, J. Pernul, S. Gebert +9
We report on the systematic study of infrared/terahertz spectra of photocurrents in (Bi,Sb)Te based three dimensional topological insulators. We demonstrate that in a wide range of…
Electrical resistance of individual defects at a topological insulator surface
Felix Lüpke, Markus Eschbach, Tristan Heider +10
Three-dimensional topological insulators host surface states with linear dispersion, which manifest as a Dirac cone. Nanoscale transport measurements provide direct access to the t…
Reinventing Solid State Electronics: Harnessing Quantum Confinement in Bismuth Thin Films
Farzan Gity, Lida Ansari, Martin Lanius +4
Solid state electronics relies on the intentional introduction of impurity atoms or dopants into a semiconductor crystal and/or the formation of junctions between different materia…
Opto-Electronic Characterization of Three Dimensional Topological Insulators
Helene Plank, Sergey N. Danilov, Vasily V. Bel'kov +6
We demonstrate that the terahertz/infrared radiation induced photogalvanic effect, which is sensitive to the surface symmetry and scattering details, can be applied to study the hi…
Topological states and phase transitions in SbTe-GeTe multilayers
Thuy-Anh Nguyen, Dirk Backes, Angadjit Singh +7
Topological insulators (TIs) are bulk insulators with exotic 'topologically protected' surface conducting modes. It has recently been pointed out that when stacked together, intera…
Disentangling surface and bulk transport in topological-insulator - junctions
D. Backes, D. Huang, R. Mansell +7
By combining -type and -type topological insulators, vertically stacked - junctions can be formed, allowing to position the Ferm…
$\mbox{Bi}_{1}\mbox{Te}_{1}$: a dual topological insulator
Markus Eschbach, Martin Lanius, Chengwang Niu +15
A combined theoretical and experimental study reveals evidence for the dual topological insulating character of the stoichiometric natural superlattice phase $\mathrm{Bi_{1}Te_{1}}…
Photon Drag Effect in (BiSb)Te Three Dimensional Topological Insulators
H. Plank, L. E. Golub, S. Bauer +10
We report on the observation of a terahertz radiation induced photon drag effect in epitaxially grown - and -type (BiSb)Te three dimensional topolog…
Realization of a vertical topological p-n junction in epitaxial heterostructures
Markus Eschbach, Ewa Mlynczak, Jens Kellner +17
3D topological insulators are a new state of quantum matter which exhibits both a bulk band structure with an insulating energy gap as well as metallic spin-polarized Dirac fermion…
Tuning the Dirac point to the Fermi level in the ternary topological insulator (BiSb)Te
Jens Kellner, Markus Eschbach, Jörn Kampmeier +9
In order to stabilize Majorana excitations within vortices of proximity induced topological superconductors, it is mandatory that the Dirac point matches the Fermi level rather exa…
