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…
Ultrafast photocurrents at the surface of the three-dimensional topological insulator
Lukas Braun, Gregor Mussler, Andrzej Hruban +6
Topological insulators constitute a new and fascinating class of matter with insulating bulk yet metallic surfaces that host highly mobile charge carriers with spin-momentum lockin…
Growth, characterization, and transport properties of ternary (Bi1-xSbx)2Te3 topological insulator layers
C. Weyrich, M. Drögeler, J. Kampmeier +12
Ternary (Bi1-xSbx)2Te3 films with an Sb content between 0 and 100% were deposited on a Si(111) substrate by means of molecular beam epitaxy. X-ray diffraction measurements confirm…
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…
Simultaneous Localization of Electrons in different -valleys in Ge/Si Quantum Dot Structures
Aigul Zinovieva, Natalia Stepina, Anatoly Dvurechenskii +4
In the present work the possibility of simultaneous localization of two electrons in and valleys in ordered structures with Ge/Si(001) quantum dots (QD) was ver…
