Magnetic field mixing and splitting of bright and dark excitons in monolayer MoSe2
Zhengguang Lu, Daniel Rhodes, Zhipeng Li +9
Monolayers of semiconducting transition metal dichalcogenides (TMDCs) with unique spin-valley contrasting properties and remarkably strong excitonic effects continue to be a subjec…
Observation of cyclotron antiresonance in the topological insulator Bi2Te3
S. V. Dordevic, Hechang Lei, C. Petrovic +3
We report on the experimental observation of a cyclotron antiresonance in a canonical 3D topological insulator BiTe. Magneto-reflectance response of single crystal BiTe…
Chiral Landau levels in Weyl semimetal NbAs with multiple topological carriers
Xiang Yuan, Zhongbo Yan, Chaoyu Song +21
Recently, Weyl semimetals have been experimentally discovered in both inversion-symmetry-breaking and time-reversal-symmetry-breaking crystals. The non-trivial topology in Weyl sem…
Measurement and tricubic interpolation of the magnetic field for the OLYMPUS experiment
J. C. Bernauer, J. Diefenbach, G. Elbakian +15
The OLYMPUS experiment used a 0.3 T toroidal magnetic spectrometer to measure the momenta of outgoing charged particles. In order to accurately determine particle trajectories, kno…
Temperature-driven massless Kane fermions in HgCdTe crystals: verification of universal velocity and rest-mass description
F. Teppe, M. Marcinkiewicz, S. S. Krishtopenko +15
It has recently been shown that the electronic states in bulk gapless HgCdTe offer another realization of pseudo-relativistic three-dimensional particles in a condensed matter syst…
High Photoresponsivity and Short Photo Response Times in Few-Layered WSe Transistors
Nihar R. Pradhan, Jonathan Ludwig, Zhengguang Lu +6
Here, we report the photoconducting response of field-effect transistors based on three atomic layers of chemical vapor transport grown WSe crystals mechanically exfoliated ont…
Pronounced photovoltaic response from multi-layered transition-metal dichalcogenides PN-junctions
Shahriar Memaran, Nihar R. Pradhan, Zhengguang Lu +7
Transition metal dichalcogenides (TMDs) are layered semiconductors with indirect band gaps comparable to Si. These compounds can be grown in large area, while their gap(s) can be t…
Valley Splitting and Polarization by the Zeeman Effect in Monolayer MoSe2
Yilei Li, Jonathan Ludwig, Tony Low +12
We have measured circularly polarized photoluminescence in monolayer MoSe2 under perpendicular magnetic fields up to 10 T. At low doping densities, the neutral and charged excitons…
Cyclotron resonance of single valley Dirac fermions in gapless HgTe quantum well
J. Ludwig, Yu. B. Vasilyev, N. N. Mikhailov +4
We report on Landau level spectroscopy studies of two HgTe quantum wells (QWs) near or at the critical well thickness, where the band gap vanishes. In magnetic fields up to =16T…
LaAlO3 stoichiometry found key to electron liquid formation at LaAlO3/SrTiO3 interfaces
M. P. Warusawithana, C. Richter, J. A. Mundy +17
Emergent phenomena, including superconductivity and magnetism, found in the two-dimensional electron liquid (2-DEL) at the interface between the insulators LaAlO3 and SrTiO3 distin…
