Observation of single antiferromagnetic magnon modes through tunnelling spectroscopy of spin-1/2 Kitaev system a-RuCl3
Servet Ozdemir, Mikhail Kashchenko, Kostya S. Novoselov
The small-gap room-temperature semiconductor a-RuCl3, which is known to undergo a Mott-Hubbard transition at low temperatures, is one of the most promising candidates for realisati…
Optical probing of Wigner crystallization in monolayer WSe via diffraction of longitudinal excitons
Artem N. Abramov, Emil Chiglintsev, Tatiana Oskolkova +5
Monolayer transition metal dichalcogenides (TMDs) are characterized by relatively large carrier effective masses and suppressed screening of the Coulomb interaction, which substant…
Universal reconstructive polarimetry with graphene-metal infrared photodetectors
Valentin Semkin, Kirill Kapralov, Ilya Mazurenko +8
Recent advent of smart photodetectors, where in-situ tuning of responsivity enables the reconstruction of light intensity, polarization and spectrum by a single device, has revolut…
Giant exciton binding energy in bulk CrCl3
Georgy Ermolaev, Tagir Mazitov, Anton Minnekhanov +20
Van der Waals (vdW) materials, with their unique combination of electronic, optical, and magnetic properties, are emerging as promising platforms for exploring excitonic phenomena.…
Probing the features of electron dispersion by tunneling between slightly twisted bilayer graphene sheets
Alexey A. Sokolik, Azat F. Aminov, Evgenii E. Vdovin +6
Tunneling conductance between two bilayer graphene (BLG) sheets separated by 2 nm-thick insulating barrier was measured in two devices with the twist angles between BLGs less than…
Enhanced Terahertz Thermoelectricity via Engineered van Hove Singularities and Nernst Effect in Moiré Superlattices
L. Elesin, A. L. Shilov, S. Jana +14
Thermoelectric materials, long explored for energy harvesting and thermal sensing, convert heat directly into electrical signals. Extending their application to the terahertz (THz)…
