Landau level spectroscopy of PbSnSe topological crystalline insulator
Kristupas Kazimieras Tikuišis, Jan Wyzula, Lukáš Ohnoutek +8
We report on an infrared magneto-spectroscopy study of PbSnSe, a topological crystalline insulator. We have examined a set of samples, all in the inverted regime of ele…
Ultra-fast quantum-well infared photodetectors operating at 10μm with flat response up to 70GHz at room temperature
M. Hakl, Q. Y. Lin, S. Lepillet +9
III-V semiconductor mid-infrared photodetectors based on intersubband transitions hold a great potential for ultra-high-speed operation up to several hundreds of GHz. In this work…
The energy scale of Dirac electrons in Cd3As2
M. Hakl, S. Tchoumakov, I. Crassee +15
Cadmium arsenide (Cd3As2) has recently became conspicuous in solid-state physics due to several reports proposing that it hosts a pair of symmetry-protected 3D Dirac cones. Despite…
Non-uniform carrier density in CdAs evidenced by optical spectroscopy
I. Crassee, E. Martino, C. C. Homes +13
We report the detailed optical properties of CdAs crystals in a wide parameter space: temperature, magnetic field, carrier concentration and crystal orientation. We investi…
Magneto-optical signature of massless Kane electrons in Cd3As2
A. Akrap, M. Hakl, S. Tchoumakov +21
We report on optical reflectivity experiments performed on Cd3As2 over a broad range of photon energies and magnetic fields. The observed response clearly indicates the presence of…
Strong interband Faraday rotation in 3D topological insulator Bi2Se3
L. Ohnoutek, M. Hakl, M. Veis +11
The Faraday effect is a representative magneto-optical phenomenon, resulting from the transfer of angular momentum between interacting light and matter in which time-reversal symme…
