Infrared nanoscopy down to liquid helium temperatures
D. Lang, J. Döring, T. Nörenberg +7
We introduce a scattering-type scanning near-field infrared microscope (s-SNIM) for the local scale near- field sample analysis and spectroscopy from room (RT) down to liquid heliu…

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…

Doubly dressed bosons - exciton-polaritons in a strong terahertz field
B. Piętka, N. Bobrovska, D. Stephan +12
We demonstrate the existence of a novel quasiparticle: an exciton in a semiconductor doubly dressed with two photons of different wavelengths: near infrared cavity photon and terah…
