Surface Plasmon Instability Leading to Emission of Radiation

Godfrey Gumbs, Andrii Iurov, Danhong Huang +1

We propose a new energy conversion approach from a dc electric field to a terahertz wave based on hybrid semiconductors by combining two-dimensional (2D) crystalline layers and a t…

Controlling quantum-dot light absorption and emission by a surface-plasmon field

Danhong Huang, Michelle Easter, Godfrey Gumbs +4

The possibility for controlling the probe-field optical gain and absorption switching and photon conversion by a surface-plasmon-polariton near field is explored for a quantum dot…

Resonant Scattering of Surface Plasmon Polaritons by Dressed Quantum Dots

Danhong Huang, Michelle Easter, Godfrey Gumbs +4

The resonant scattering of surface plasmon-polariton waves by embedded semiconductor quantum dots above the dielectric/metal interface is explored in the strong-coupling regime. In…

Plasmons in a Superlattice of Fullerenes or Metallic Shells

Antonios Balassis, Godfrey Gumbs

A theory for the collective plasma excitations in a linear periodic array of spherical two-dimensional electron gases (S2DEGs) is presented. This is a simple model for an ultra thi…

Combined Effect of Stacking and Magnetic Field on Plasmon Excitations in Bilayer Graphene

Jhao-Ying Wu, Godfrey Gumbs, Ming-Fa Lin

The electronic excitations of bilayer graphene (BLG) under a magnetic field are investigated with the use of the Peierls tight-binding model in conjunction with random-phase approx…

Revealing Hofstadter Spectrum for Graphene in a Periodic Potential

Godfrey Gumbs, Andrii Iurov, Danhong Huang +1

We calculate the energy bands for graphene monolayers when electrons move through a periodic electrostatic potential in the presence of a uniform perpendicular magnetic field. We c…

Modeling Anisotropic Plasmon Excitations in Self-Assembled Fullerenes

Andrii Iurov, Godfrey Gumbs, Bo Gao +1

The plasmon excitations in Coulomb-coupled spherical two-dimensional electron gases (S2DEGs) reveal an interesting dependence on the displacement vector between the centers of the…
