High-harmonic generation enhancement with graphene heterostructures
Irati Alonso Calafell, Lee A. Rozema, Alessandro Trenti +9
We investigate high-harmonic generation in graphene heterostructures consisting of metallic nanoribbons separated from a graphene sheet by either a few-nanometer layer of aluminum…
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…
The ultrafast dynamics and conductivity of photoexcited graphene at different Fermi energies
A. Tomadin, S. M. Hornett, H. I. Wang +10
For many of the envisioned optoelectronic applications of graphene it is crucial to understand the sub-picosecond carrier dynamics immediately following photoexcitation, as well as…
