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…
VO2 films grown on TiO2 sub-layer: influence of thickness on structural, electrical and optical properties
M. E. Kutepov, V. E. Kaydashev, D. V. Stryukov +7
Vanadium dioxide with metal-to-insulator transition (MIT) that is triggered by heat, current or light is a promising material for modern active THz/mid-IR metasurfaces and all-opti…
Limiting performance of graphene bilayer sub-terahertz detectors at large induced band gap
Elena I. Titova, Mikhail A. Kashchenko, Andrey V. Miakonkikh +8
Electrically induced junctions in graphene bilayer (GBL) have shown superior performance for detection of sub-THz radiation at cryogenic temperatures, especially upon electri…
