Electronic, optical, vibrational and thermodynamic properties of phaBN structure: a first principles study
J. M. Pontes, N. F. Frazão, David L. Azevedo +1
In 2015, a new two dimensional (2D) carbon allotrope, called phagraphene, was theoretically proposed. Based on this structure, we propose here a new boron nitride structure called…
Electronic transport in disordered graphene superlattices with scale-free correlated barrier spacements
Anderson L. R. Barbosa, Jonas R. F. Lima, Ícaro S. F. Bezerra +1
A transfer matrix approach is used to study the electronic transport in graphene superlattices with long-range correlated barrier spacements. By considering the low-energy electron…
Effects of Fermi velocity engineering in magnetic graphene superlattices
Ícaro S. F. Bezerra, Jonas R. F. Lima
In this work we investigate theoretically the influence of a Fermi velocity modulation in the electronic and transport properties of magnetic graphene superlattices. We solve the e…
Spin current generation and control in carbon nanotubes by combining rotation and magnetic field
Márcio M. Cunha, Jonas R. F. Lima, Fernando Moraes +2
We study the quantum dynamics of ballistic electrons in rotating carbon nanotubes in the presence of a uniform magnetic field. When the field is parallel to the nanotube axis, the…
Perfect valley filter controlled by Fermi velocity modulation in graphene
A. R. S. Lins, Jonas R. F. Lima
In this work we investigate the effects of a Fermi velocity modulation in a valley filter in graphene created by a combination of a magnetic and electric barrier. With the effectiv…
