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…
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…
Sub-nm wide electron channels protected by topology
Christian Pauly, Bertold Rasche, Klaus Koepernik +11
Helical locking of spin and momentum and prohibited backscattering are the key properties of topologically protected states. They are expected to enable novel types of information…
Room temperature high frequency transport of Dirac fermions in epitaxially grown Sb_2Te_3 based topological insulators
P. Olbrich, L. E. Golub, T. Herrmann +11
We report on the observation of photogalvanic effects in epitaxially grown Sb_2Te_3 three-dimensional (3D) topological insulators (TI). We show that asymmetric scattering of Dirac…
