Observation of plasmon-phonon coupling in natural 2D graphene-talc heterostructures
Ingrid D. Barcelos, Alisson R. Cadore, Ananias B. Alencar +8
Two-dimensional (2D) materials occupy noteworthy place in nanophotonics providing for subwavelength light confinement and optical phenomena dissimilar to those of their bulk counte…
Enhancing the response of NH3 graphene-sensors by using devices with different graphene-substrate distances
A. R. Cadore, E. Mania, A. B. Alencar +7
Graphene (G) is a two-dimensional material with exceptional sensing properties. In general, graphene gas sensors are produced in field effect transistor configuration on several su…
Soliton instability and fold formation in laterally compressed few-layer graphene
Amauri Libério de Lima, Lucas A. M. Müssnich, Taíse M. Manhabosco +3
We investigate -- through simulations and analytical calculations -- the consequences of uniaxial lateral compression applied to the upper layer of few-layer graphene. The simulati…
Stability of extended defects on boron nitride and graphene monolayers: the role of chemical environment
L. C. Gomes, S. S. Alexandre, H. Chacham +1
We perform ab initio calculations that indicate that the relative stability of antiphase boundaries (APB) with armchair and zigzag chiralities in monolayer boron nitride (BN) is de…
Non-hexagonal-ring defects and structures induced by strain in graphene and in functionalized graphene
Joice da Silva-Araújo, A. J. M. Nascimento, Hélio Chacham +1
We perform {\textit ab initio} calculations for the strain-induced formation of non-hexagonal-ring defects in graphene, graphane (planar CH), and graphenol (planar COH). We find th…
Bistability, softening, and quenching of magnetic moments in Ni-filled carbon nanotubes
Eduardo M. Diniz, Ricardo W. Nunes, Hélio Chacham +1
The authors apply first-principles calculations to investigate the interplay between structural, electronic, and magnetic properties of nanostructures composed of narrow nanotubes…
