Tuning of exciton type by environmental screening
Igor L. C. Lima, M. V. Milošević, F. M. Peeters +1
We theoretically investigate the binding energy and electron-hole (e-h) overlap of excitonic states confined at the interface between two-dimensional materials with type-II band al…
Ultrasensitive acoustic graphene plasmons in a graphene-transition metal dichalcogenide heterostructure: strong plasmon-phonon coupling and wavelength sensitivity enhanced by a metal screen
Ícaro R. Lavora, Z. H. Tao, H. M. Dongd +3
Acoustic plasmons in graphene exhibit strong confinement induced by a proximate metal surface and hybridize with phonons of transition metal dichalcogenides (TMDs) when these mater…
Tunable coupling of terahertz Dirac plasmons and phonons in transition metal dicalchogenide-based van der Waals heterostructures
I. R. Lavor, Andrey Chaves, F. M. Peeters +1
Dirac plasmons in graphene hybridize with phonons of transition metal dichalcogenides (TMDs) when the materials are combined in so-called van der Waals heterostructures (vdWh), thu…
Probing the structure and composition of van der Waals heterostructures using the nonlocality of Dirac plasmons in the terahertz regime
I. R. Lavor, L. S. R. Cavalcante, Andrey Chaves +2
Dirac plasmons in graphene are very sensitive to the dielectric properties of the environment. We show that this can be used to probe the structure and composition of van der Waals…
Effect of zitterbewegung on the propagation of wave packets in ABC-stacked multilayer graphene: an analytical and computational approach
I. R. Lavor, D. R. da Costa, Andrey Chaves +4
The time evolution of a low-energy two-dimensional Gaussian wave packet in ABC-stacked -layer graphene (ABC-NLG) is investigated. Expectation values of the position of c…
Valley filtering using electrostatic potentials in bilayer graphene
D. R. da Costa, A. Chaves, S. H. R. Sena +2
Propagation of an electron wave packet through a quantum point contact (QPC) defined by electrostatic gates in bilayer graphene is investigated. The gates provide a bias between th…
