Influence of Dielectric Environment on Role of Spin-Orbit Interaction for Image Potentials
Godfrey Gumbs, Oleksiy Roslyak, Danhong Huang +1
We present a formalism for calculating the image potential for a two-dimensional electron gas (2DEG) with Rashba spin-orbit interaction (SOI) as well as for a 2D topological insula…
Anisotropic plasmon-coupling dimerization of a pair of spherical electron gases
Godfrey Gumbs, Andrii Iurov, Antonios Balassis +1
We have discovered a novel feature in the plasmon excitations for a pair of Coulomb-coupled non- concentric spherical two-dimensional electron gases (S2DEGs). Our results show that…
Electronic properties of closed cage nanometer-size spherical graphitic particles
Godfrey Gumbs, Antonios Balassis, Andrii Iurov +1
We investigate the localization of charged particles by the image potential of spherical shells, such as fullerene buckyballs. These "spherical image states" exist within surface p…
