Electrical tunability of terahertz nonlinearity in graphene
Sergey Kovalev, Hassan A. Hafez, Klaas-Jan Tielrooij +15
Graphene is conceivably the most nonlinear optoelectronic material. Its nonlinear optical coefficients in the terahertz (THz) frequency range surpass those of other materials by ma…
Disentangling complex current pathways in a metallic Ru/Co bilayer nanostructure using THz spectroscopy
Nicolas S. Beermann, Savio Fabretti, Karsten Rott +3
Many modern spintronic technologies, such as spin valves, spin Hall applications, and spintronic THz emitters, are based on electrons crossing buried internal interfaces within met…
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…
Out-of-plane heat transfer in van der Waals stacks: electron-hyperbolic phonon coupling
K. J. Tielrooij, N. C. H. Hesp, A. Principi +20
Van der Waals heterostructures have emerged as promising building blocks that offer access to new physics, novel device functionalities, and superior electrical and optoelectronic…
Competing Ultrafast Energy Relaxation Pathways in Photoexcited Graphene
Soeren A. Jensen, Zoltan Mics, Ivan Ivanov +5
For most optoelectronic applications of graphene a thorough understanding of the processes that govern energy relaxation of photoexcited carriers is essential. The ultrafast energy…
