Electron Energy Loss Function of Silicene and Germanene Multilayers on Silver
L. Rast, V. K. Tewary
We calculate electron energy loss spectra (EELS) for composite plasmonic structures based on silicene and germanene. A continued-fraction expression for the effective dielectric fu…

Stratified Graphene-Noble Metal Systems for Low-Loss Plasmonics Applications
L. Rast, T. J. Sullivan, V. K. Tewary
We propose a composite layered structure for tunable, low-loss plasmon resonances, which con- sists of a noble-metal thin film coated in graphene and supported on a hexagonal boron…

Manipulation of graphene's dynamic ripples by local harmonic out-of-plane excitation
A. Smolyanitsky, V. K. Tewary
With use of carefully designed molecular dynamics simulations, we demonstrate tuning of dynamic ripples in free-standing graphene by applying a local out-of-plane sinusoidal excita…
