We have calculated and investigated the electronic states, dynamical polarization function
and the plasmon excitations for α-T 3 nanoribbons with armchair-edge termination. The …

We calculate the dielectric function and plasmonic response of armchair (aGNRs) and
zigzag (zGNRs) graphene nanoribbons using the self-consistent-field approach within the …

The optical response of quasi-one-dimensional systems is often dominated by tightly bound
excitons that significantly influence their basic electronic properties. Despite their importance …

Fundamental symmetries in thermoelectric quantum transport, beyond Onsagers relations,
were predicted two decades ago but have to date not been observed in experiments. Recent …

Chemically derived graphene nanoribbons and quantum dots are unique nanostructures
that offer more possibilities than 2D and 3D systems to tune their electronic properties due to …

Plasmon excitations in metallic armchair graphene nanoribbons are investigated using the
random phase approximation. An exact analytical expression for the polarization function of …

Using a nearest-neighbor tight-binding model we investigate quantum effects of plasmons
on few-nanometer wide graphene nanoribbons, both for zigzag and armchair edge …

Using Maxwell's equations for the incoming and outgoing electromagnetic field, in
interaction with a metallic arm-chair graphene nanoribbon (AGNR), and the relationship …

We address the possibility of atomic-scale control of the plasmon modes of graphene
nanostructures. Using the time-dependent many-body approach we show that for the zigzag …

In this Letter, a graphene-based terahertz plasmonic waveguide is proposed. The proposed
structure benefits from the enhanced confinement and increased attenuation length of …
