Enhancement of terahertz response in a microstructure-integrated-type-II Dirac semimetal

open access: yesAIP Advances, 2023
Terahertz detection technology has been confronted with formidable impediments, notably the paucity of sensitivity and operating temperature for photodetectors based on traditional bulk materials. In an attempt to surmount the difficulties, we propose an

Terahertz Detectors based on graphene

open access: yesJournal of Physics: Conference Series, 2013
In this study we present magnetotransport an magnetooptical data obtained in the magnetic field range 0T < B < 7T at detectors patterned in Corbino geometry on epitaxial graphene wafer using a Ge detector. We observed the cyclotron resonance of charge carriers in these wafers by measurement of the transmission of THz wafes through the unpatterned

Molecular Junctions for Terahertz Switches and Detectors

open access: yesNano Letters, 2023
Abstract Molecular electronics targets tiny devices exploiting the electronic properties of the molecular orbitals, which can be tailored and controlled by the chemical structure/conformation of the molecules. Many functional devices have been experimentally demonstrated; however, these devices were operated in the low frequency domain (mainly,

Compact and ultra-efficient broadband plasmonic terahertz field detector

open access: yesNature Communications, 2019
Most efficient terahertz detection schemes rely on complex free space optics and require high-power lasers. Here, the authors report an integrated plasmonic terahertz detector on a silicon photonics platform, with 2.5 THz bandwidth and a 65 dB dynamical ...

An analytical model for terahertz detection in cylindrical surrounding-gate MOSFETs

open access: yesAIP Advances, 2018
An analytical model for detection of terahertz radiation by plasma wave in cylindrical surrounding-gate (SRG) MOSFETs is presented. In comparison with traditional drain-current models, the rectification response of terahertz signal due to current self ...
