Perfect absorption by metal-contacted two-dimensional systems with ultra-proximate reflectors
Kirill Kapralov, Vladislav Atlasov, Alina Khisameeva +2
Electromagnetic absorbance by most two-dimensional electron systems is typically well below unity, which hinders both practical applications in photodetection and fundamental studi…
Photocurrent at oblique illumination and reconstruction of wavefront direction with 2d photodetectors
Kirill Kapralov, Vladislav Atlasov, Alina Khisameeva +3
Many contemporary photodetectors operate beyond the readout of light intensity and enable the reconstruction of spectrum and polarization at the single-pixel level. However, the de…
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…
All-in-plane image sensors free from readout integrated circuits
Kirill Kapralov, Ilya Mazurenko, Elizaveta Tarkaeva +12
High resolution image sensors require electrical access to each individual pixel for signal readout. Such access is especially challenging for ultra-miniaturized pixels, for hetero…
Graphene Zero-Bias Sub-Terahertz Turnkey Detector with Above 43 GHz Bandwidth
E. I. Titova, A. Titchenko, M. Titova +16
High-frequency terahertz (THz) detectors are vital for next-generation high-speed wireless communication systems. Graphene, with its high carrier mobility, broadband absorption, an…
Multifunctional 2d infrared photodetectors enabled by asymmetric singular metasurfaces
Valentin Semkin, Aleksandr Shabanov, Kirill Kapralov +9
Two-dimensional materials offering ultrafast photoresponse suffer from low intrinsic absorbance, especially in the mid-infrared wavelength range. Challenges in 2d material doping f…
Testing the tomographic Fermi liquid hypothesis with high-order cyclotron resonance
Ilia Moiseenko, Erwin Mönch, Kirill Kapralov +3
Recent theoretical studies of carrier-carrier scattering in degenerate two-dimensional systems have revealed radically different relaxation times for odd and even angular harmonics…
Ballistic-to-hydrodynamic transition and collective modes for two-dimensional electron systems in magnetic field
Kirill Kapralov, Dmitry Svintsov
The recent demonstrations of viscous hydrodynamic electron flow in two-dimensional electron systems poses serious questions to the validity of existing transport theories, includin…
Cyclotron resonance overtones and near-field magnetoabsorption via terahertz Bernstein modes in graphene
D. A. Bandurin, E. Mönch, K. Kapralov +8
Two-dimensional electron systems subjected to a perpendicular magnetic field absorb electromagnetic radiation via the cyclotron resonance (CR). Here we report a qualitative breach…
Plasmon damping in electronically open systems
Kirill Kapralov, Dmitry Svintsov
Rapid progress in electrically-controlled plasmonics in solids poses a question about effects of electronic reservoirs on the properties of plasmons. We find that plasmons in elect…
