Electrostatic interactions between graphene layers and their environment
J. Sabio, C. Seoanez, S. Fratini +3
We analyze the electrostatic interactions between a single graphene layer and a SiO susbtrate, and other materials which may exist in its environment. We obtain that the leadin…
Surface dissipation in nanoelectromechanical systems: Unified description with the standard tunneling model and effects of metallic electrodes
C. Seoanez, F. Guinea, A. H. Castro Neto
By modifying and extending recent ideas [C. Seoanez et al., Europhys. Lett. 78, 60002 (2007)], a theoretical framework to describe dissipation processes in the surfaces of vibratin…
Dissipation in graphene and nanotube resonators
C. Seoanez, F. Guinea, A. H. Castro Neto
Different damping mechanisms in graphene nanoresonators are studied: charges in the substrate, ohmic losses in the substrate and the graphene sheet, breaking and healing of surface…
Friction of the surface plasmon by high-energy particle-hole pairs: Are memory effects important?
Cesar Seoanez, Guillaume Weick, Rodolfo A. Jalabert +1
We show that the dynamics of the surface plasmon in metallic nanoparticles damped by its interaction with particle-hole excitations can be modelled by a single degree of freedom co…
Dissipation due to two-level systems in nano-mechanical devices
C. Seoanez, F. Guinea, A. H. Castro Neto
We analyze the dissipation of the frequency vibrations of nano-mechanical devices. We show that the coupling between flexural modes and two-level systems leads to sub-ohmic dissipa…
