Terahertz s-SNOM reveals nonlocal nanoscale conductivity of graphene
Henrik B. Lassen, William V. Carstensen, Leonid Iliushyn +4
As photonic and electronic technologies approach nanometre length scales and terahertz operating speeds, electrical conductivity can no longer be treated as a purely local material…

Dielectric permittivity extraction of MoS nanoribbons using THz nanoscopy
Henrik B. Lassen, William V. Carstensen, Denys I. Miakota +4
The nanoscale optical properties of high-quality MoS nanoribbons are investigated using THz nanoscopy based on a scattering-type scanning probe. The nanoribbons comprise a mult…
