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…

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…

Coherent ultrafast spin-dynamics probed in three dimensional topological insulators

F. Boschini, M. Mansurova, G. Mussler +12

Topological insulators are candidates to open up a novel route in spin based electronics. Different to traditional ferromagnetic materials, where the carrier spin-polarization and…

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…
