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…
Optical selection rules of zigzag graphene nanoribbons
V. A. Saroka, M. V. Shuba, M. E. Portnoi
We present an analytical tight-binding theory of the optical properties of graphene nanoribbons with zigzag edges. Applying the transfer matrix technique to the nearest-neighbor ti…
