Conditions for the occurrence of Coulomb blockade in phosphorene quantum dots at room temperature
H. A. Melo, M. A. Lino, D. R. da Costa +4
We study the addition energy spectra of phosphorene quantum dots focusing on the role of dot size, edges passivation, number of layers and dielectric constant of the substrate wher…
Excitonic gaps and exciton binding energies in multilayer phosphorene quantum dots
M. A. Lino, J. S. de Sousa, D. R. da Costa +3
Dielectric screening is greatly important to an accurate calculation of the exciton binding energies in two-dimensional materials. In this work, we calculate the dielectric functio…
Interferometry of Klein tunnelling electrons in graphene quantum rings
D. J. P. de Sousa, Andrey Chaves, J. M. Pereira +1
We theoretically study a current switch that exploits the phase acquired by a charge carrier as it tunnels through a potential barrier in graphene. The system acts as an interferom…
