Quantum spin Hall effect on germanene nanoroad embedded in a completely hydrogenated germanene
L. Seixas, J. E. Padilha, A. Fazzio
We show that germanene nanoroads embedded in a completely hydrogenated germanene (germanane) exhibits a quantum spin Hall effect (QSHE). These nanoroads can be obtained experimenta…
Bilayer graphene dual-gate nanodevice: An ab initio simulation
J. E. Padilha, Matheus P. Lima, A. J. R. da Silva +1
We study the electronic transport properties of a dual-gated bilayer graphene nanodevice via first principles calculations. We investigate the electric current as a function of gat…
Energetics and stability of vacancies in carbon nanotubes
José Eduardo Padilha, Rodrigo Garcia Amorim, Alexandre Reily Rocha +2
In this work we present ab initio calculations of the formation energies and stability of different types of multi-vacancies in carbon nanotubes. We demonstrate that, as in the cas…
