Design of wideband terahertz pyroelectric detector based on metasurface [PDF]

open access: yesJournal of Hebei University of Science and Technology
In order to solve the problems of low absorption efficiency and small frequency range of traditional terahertz (THz) detectors, a broadband terahertz metasurface pyroelectric detector was proposed by combining a dual metasurface absorption array ...

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

Terahertz single pixel imaging based on a Nipkow disk [PDF]

open access: yes, 2012
We describe a terahertz single pixel imaging system based on a Nipkow disk. Nipkow disks have been used for fast scanning imaging systems since the first experimental television was invented in 1926.

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,
