Stark shift of excitons and trions in two-dimensional materials
L. S. R. Cavalcante, D. R. da Costa, G. A. Farias +2
The effect of an external in-plane electric field on neutral and charged exciton states in two-dimensional (2D) materials is theoretically investigated. These states are argued to…
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…
Plasmons in bias-induced topological phase transition in black phosphorus
D. J. P. de Sousa, L. S. R. Cavalcante, Andrey Chaves +2
We investigate the plasmons in bilayer black phosphorus (BP) with bias-driven formation of Dirac cones, by developing an effective two-band Hamiltonian that captures this electroni…
