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…
Electron-hole collision-limited resistance of gapped graphene
Arseny Gribachov, Vladimir Vyurkov, Dmitry Svintsov
Collisions between electrons and holes can dominate the carrier scattering in clean graphene samples in the vicinity of charge neutrality point. While electron-hole limited resista…
Zero-bias photodetection in 2d materials via geometric design of contacts
Valentin A. Semkin, Aleksandr V. Shabanov, Dmitry A. Mylnikov +4
Structural or crystal asymmetry are necessary conditions for emergence of zero-bias photocurrent in light detectors. Structural asymmetry has been typically achieved via dopi…
Ultralow-noise terahertz detection by p-n junctions in gapped bilayer graphene
Elena Titova, Dmitry Mylnikov, Mikhail Kashchenko +6
Graphene shows a strong promise for detection of terahertz (THz) radiation due to its high carrier mobility, compatibility with on-chip waveguides and transistors, and small heat c…
Terahertz photoconductivity in bilayer graphene transistors: evidence for tunneling at gate-induced junctions
Dmitry Mylnikov, Elena I. Titova, Mikhail A. Kashchenko +6
Photoconductivity of novel materials is the key property of interest for design of photodetectors, optical modulators, and switches. Despite the photoconductivity of most novel 2d…
Signatures of non-local conductivity in near-field microscopy
Mikhail Khavronin, Dmitry Svintsov
We propose and theoretically substantiate a new method to study the non-local conductivity of two-dimensional electron systems (2DES) using the tools of near-field microscopy. We s…
