Plasmonic interferometry is a rapidly growing area of research with huge potential for applications in the terahertz frequency range. In this Letter, we explore plasmonic interferometer based on graphene field effect transistor connected to specially designed antennas. As key result, observe helicity- and phase-sensitive conversion circularly polarized radiation into dc photovoltage caused by plasmon-interference mechanism: two plasma waves, excited at source drain part transistor, interfere...
Detectors of terahertz radiation based on field-effect transistors (FETs) are among most promising candidates for low-noise passive signal rectification both in imaging systems and wireless communications. However, it was not realised so far that geometric asymmetry common FET with respect to source-drain interchange is a strong objective photovoltage harvesting. Here, we break the traditional scheme reveal optimally-asymmetric structure providing maximization THz responsivity. We fabricate...
Abstract Wastewater-based epidemiology (WBE) can help mitigate the spread of respiratory infections through early detection viruses, pathogens, and other biomarkers in human waste. The need for sample collection, shipping, testing facilities drives up cost WBE hinders its use rapid isolation environments with small populations low-resource settings. Given ubiquitousness regular outbreaks syncytial virus, SARS-CoV-2 various influenza strains, there is a rising low-cost easy-to-use biosensing...

Topological materials are at the forefront of quantum research, offering tremendous potential for next-generation energy and information devices. However, current investigation these remains largely focused on performance often neglects crucial aspect sustainability. Recognizing pivotal role sustainability in addressing global pollution, carbon emissions, resource conservation, ethical labor practices, we present a comprehensive evaluation topological based their environmental impact. Our...
Here, we report on our recent efforts to develop of a photodetector based single-layer graphene two-terminal device the sapphire substrate. Our detector operates at $1.55 \mu \mathrm{m}$, which corresponds telecom window. We have demonstrated that under zero bias conditions room temperature, and signal-to-noise ratio reaches 45dB. The measured frequency bandwidth 20GHz is limited by available experimental equipment.
High optical phonon energy and short electron thermalization time in graphene enable the creation of fast sensitive thermoelectric detectors. Here, we demonstrate such a photodetector for mid-infrared region (9.3 µm) which is challenging task due to small absorption by single layer this wavelength range. The shows response 20 µs scales with square device size can be shortened miniaturized devices.
Abstract The growing requirements for mobile communication networks (data transfer rates over 100 Gbps) makes it necessary to use carrier signal with a frequency of at least GHz. This requires the development cheap and broadband sub-terahertz (sub-THz) detectors. Here we report on our recent efforts toward heterodyne sub-THz detector based single layer graphene two-terminal device integrated bowtie antenna sapphire substrate. Our operates 140 GHz, which corresponds maximum transmission THz...
