Plasmon dissipation in gapped-graphene open systems at finite temperature
Andrii Iurov, Godfrey Gumbs, Danhong Huang +1
Numerical and closed-form analytic expressions for plasmon dispersion relations and rates of dissipation are first obtained at finite-temperatures for free-standing gapped graphene…
Environmental Effects on the Terahertz Surface Plasmons in Epitaxial Graphene
Godfrey Gumbs, Andrii Iurov, Jhao-Ying Wu +2
In this paper, we predict the existence of low-frequency nonlocal plasmon excitations at the vacuum-surface interface of a superlattice of graphene layers interacting with a th…
Temperature-dependent Plasmons and Their Damping Rates for Graphene with a Finite Energy Bandgap
Andrii Iurov, Godfrey Gumbs, Danhong Huang +1
We obtained numerical and closed-form analytic expressions for finite-temperature plasmon dispersion relations for intrinsic graphene in the presence of a finite energy gap in the…
Coulomb Excitations for a Short Linear Chain of Metallic Shells
Liubov Zhemchuzhna, Godfrey Gumbs, Andrii Iurov +2
A self-consistent-field theory is given for the electronic collective modes of a chain containing a finite number, , of Coulomb-coupled spherical two-dimensional electron gases…
