Advantages of optical modulation in terahertz imaging for study of graphene layers
Rusnė Ivaškevičiūtė-Povilauskienė, Alesia Paddubskaya, Dalius Seliuta +7
It was demonstrated that optical modulation together with simultaneous terahertz (THz) imaging application enables an increase in contrast by an order of magnitude illustrating hen…
Ultrafast modulation in a THz graphene-based flat absorber through negative photoconductivity
Anna C. Tasolamprou, Anastasios D. Koulouklidis, Christina Daskalaki +9
We present the experimental and theoretical study of an ultrafast graphene based thin film absorption modulator for operation in the THz regime. The flat modulator is composed of a…
Carbon nanotube array as a van der Waals two-dimensional hyperbolic material
R. G. Polozkov, N. Y. Senkevich, S. Morina +3
We use an ab-initio approach to design and study a novel two-dimensional material - a planar array of carbon nanotubes separated by an optimal distance defined by the van der Waals…
Sign inversion in the terahertz photoconductivity of single-walled carbon nanotube films
Peter Karlsen, Mikhail V. Shuba, Polina P. Kuzhir +3
In recent years, there have been conflicting reports regarding the ultrafast photoconductive response of films of single walled carbon nanotubes (CNTs), which apparently exhibit ph…
Influence of nanotube length and density on the plasmonic terahertz response of single-walled carbon nanotubes
Peter Karlsen, Mikhail V. Shuba, Chris Beckerleg +8
We measure the conductivity spectra of thin films comprising bundled single-walled carbon nanotubes (CNTs) of different average lengths in the frequency range 0.3-1000 THz and temp…
A study of random resistor-capacitor-diode networks to assess the electromagnetic properties of carbon nanotube filled polymers
D. S. Bychanok, A. G. Paddubskaya, P. P. Kuzhir +4
We determined the frequency dependent effective permittivity of a large ternary network of randomly positioned resistors, capacitors, and diodes. A linear circuit analysis of such…
