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…
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)…
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…
