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…
MBE Growth of Al/InAs and Nb/InAs Superconducting Hybrid Nanowire Structures
Nicholas A. Güsken, Torsten Rieger, Benjamin Bennemann +4
We report on \textit{in situ} growth of crystalline Al and Nb shells on InAs nanowires. The nanowires are grown on Si(111) substrates by molecular beam epitaxy (MBE) without foreig…
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…
Signatures of interaction-induced helical gaps in nanowire quantum point contacts
S. Heedt, N. Traverso Ziani, F. Crépin +6
Spin-momentum locking in a semiconductor device with strong spin-orbit coupling (SOC) is a fundamental goal of nanoscale spintronics and an important prerequisite for the formation…
