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…
Tuning valley polarization in a WSe2 monolayer with a tiny magnetic field
T. Smoleński, M. Goryca, M. Koperski +5
In monolayers of semiconducting transition metal dichalcogenides, the light helicity ( or ) is locked to the valley degree of freedom, leading to the possibility of optic…
Determination of the exciton binding energy and effective masses for the methylammonium and formamidinium lead tri-halide perovskite family
Krzysztof Galkowski, Anatolie Mitioglu, Atsuhiko Miyata +8
The family of organic-inorganic halide perovskite materials has generated tremendous interest in the field of photovoltaics due to their high power conversion efficiencies. There h…
Disorder-induced stabilization of the quantum Hall ferromagnet
B. A. Piot, W. Desrat, D. K. Maude +3
We report on an absolute measurement of the electronic spin polarization of the integer quantum Hall state. The spin polarization is extracted in the vicinity of (inclu…
Measurement of Topological Berry Phase in Highly Disordered Graphene
K. Bennaceur, J. Guillemette, P. L. Lévesque +12
We have observed the quantum Hall effect (QHE) and Shubnikov-de Haas (SdH) oscillations in highly disordered graphene at magnetic fields up to 65 T. Disorder was introduced by hydr…
Indirect-to-direct band-gap crossover in few-layer MoTe
Ignacio Gutiérrez-Lezama, Ashish Arora, Alberto Ubaldini +4
We study the evolution of the band-gap structure in few-layer MoTe crystals, by means of low-temperature micro-reflectance (MR) and temperature-dependent photoluminescence (PL)…
Exciton band structure in layered MoSe2: from a monolayer to the bulk limit
Ashish Arora, Karol Nogajewski, Maciej R. Molas +2
We present the micro-photoluminescence (PL) and micro-reflectance contrast spectroscopy studies on thin films of MoSe2 with layer thicknesses ranging from a monolayer (1L) up to…
Quadexciton cascade and fine structure splitting of the triexciton in a single quantum dot
M. R. Molas, A. A. L. Nicolet, A. Babinski +1
We report the properties of emission lines associated with the cascaded recombination of a quadexciton in single GaAlAs/AlAs quantum dots, studied by means of polarization-resolved…
Band bending inversion in BiSe nanostructures
Louis Veyrat, Fabrice Iacovella, Joseph Dufouleur +8
Shubnikov-de-Haas oscillations were studied under high magnetic field in BiSe nanostructures grown by Chemical Vapor Transport, for different bulk carrier densities ranging…
Effect of electronic band dispersion curvature on de Haas-van Alphen oscillations
Jean-Yves Fortin, Alain Audouard
The effect of electronic band curvature, i.e. the deviation from parabolicity of electronic dispersion, on de Haas-van Alphen oscillations spectra is studied. Although the oscillat…
Proximity Effect in Periodic Arrays of Superconducting Nanoislands on Thin Graphite Layer
Yu. I. Latyshev, A. M. Smolovich, A. P. Orlov +2
The regular structure of superconducting nanoislands of alloy W-Ga-C was fabricated on nanothin graphite using focused ion beam. The resistance vs temperature dependence down to 1.…
