Tuning 2D hyperbolic plasmons in black phosphorus
Edo van Veen, Andrei Nemilentsau, Anshuman Kumar +4
Black phosphorus presents a very anisotropic crystal structure, making it a potential candidate for hyperbolic plasmonics, characterized by a permittivity tensor where one of the p…
Strain-induced bound states in transition-metal dichalcogenide bubbles
L. Chirolli, E. Prada, F. Guinea +2
We theoretically study the formation of single-particle bound states confined by strain at the center of bubbles in monolayers of transition-metal dichalcogenides (TMDs). Bubbles u…
Plasmon Spectrum of Single Layer Antimonene
Guus Slotman, Alexander Rudenko, Edo van Veen +3
The collective excitation spectrum of two-dimensional (2D) antimonene is calculated beyond the low energy continuum approximation. The dynamical polarizability is computed using a…
Black phosphorus: A new bandgap tuning knob
Rafael Roldán, Andres Castellanos-Gomez
Modern electronics rely on devices whose functionality can be adjusted by the end-user with an external 'knob'. A new tuning knob to modify the band gap of black phosphorus has bee…
Excitation spectrum and high energy plasmons in single- and multi-layer graphene
Shengjun Yuan, Rafael Roldán, Mikhail I. Katsnelson
In this paper we study the excitation spectrum of single- and multi-layer graphene beyond the Dirac cone approximation. The dynamical polarizability of graphene is computed using a…
Suppression of anharmonicities in crystalline membranes by external strain
Rafael Roldán, Annalisa Fasolino, Kostyantyn V. Zakharchenko +1
In practice, physical membranes are exposed to a certain amount of external strain (tension or compression), due to the environment where they are placed. As a result, the behavior…
