Effect of Energy Band Gap in Graphene on Negative Refraction through the Veselago Lens and Electron Conductance
Dipendra Dahal, Godfrey Gumbs
A remarkable property of intrinsic graphene is that upon doping, electrons and holes travel through the monolayer thick material with constant velocity which does not depend on ene…
Effect of Temperature and Doping on Plasmon Excitations for an Encapsulated Double-Layer Graphene Heterostructure
Godfrey Gumbs, Dipendra Dahal, Antonios Balassis
We perform a comprehensive analysis of the spectrum of graphene plasmons which arise when a pair of sheets are confined between conducting materials. The associated enhanced local…
Plasmon Excitations for Encapsulated Graphene
Godfrey Gumbs, Norman J. M. Horing, Andrii Iurov +1
We have developed an analytical formulation to calculate the plasmon dispersion relation for a two-dimensional layer which is encapsulated within a narrow spatial gap between two b…
