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…
Substrate effects on the exciton fine structure of black phosphorus quantum dots
J. S. de Sousa, M. A. Lino, D. R. da Costa +3
We study the size-dependent exciton fine structure in monolayer black phosphorus quantum dots (BPQDs) deposited on different substrates (isolated, Si and SiO) using a combinati…
Charging energy spectrum of black phosphorus quantum dots
M. A. Lino, J. S. de Sousa, D. R. da Costa +3
We present a theoretical study of the charging effects in single and double layer black phosphorus quantum dots (BPQDs) with lateral sizes of 2 nm and 3 nm. We demonstrate that the…
