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…
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…
Ultrafast opto-mechanical terahertz modulators based on stretchable carbon nanotube thin films
Maksim I. Paukov, Vladimir V. Starchenko, Dmitry V. Krasnikov +8
For terahertz (THz) wave applications, tunable and rapid modulation is highly required. When studied by means of optical pump-terahertz probe spectroscopy, single-walled carbon nan…
Electrically reduced optical switching threshold of VO2-based THz metasurface
V. E. Kaydashev, A. S. Slavich, I. K. Domaratskiy +5
The VO2-based THz metasurface optical switching threshold is reduced by more than five orders of magnitude to 0.32-0.4 W/cm2 due to the supply of a subthreshold electric current. M…
