Total internal reflection based super-resolution imaging for sub-IR frequencies
Lauren E. Barr, Peter Karlsen, Samuel M. Hornett +5
For measurements designed to accurately determine layer thickness, there is a natural trade-off between sensitivity to optical thickness and lateral resolution due to the angular r…
Approximations used in the analysis of signals in pump-probe spectroscopy
Peter Karlsen, Euan Hendry
In pump-probe spectroscopy, one often needs to analyse the transmission or reflection of electromagnetic waves through optically pumped media. Here, it is common practice to approx…
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…
