Atomic collapse in gapped graphene: lattice and valley effects
Jing Wang, Xiaotai Wu, Wen-Sheng Zhao +3
We study the atomic collapse phenomenon in and valley of gapped graphene. Bound states induced by Coulomb impurity in the gap turn into atomic collapse resonances as the c…

Phosphorene Junctions as a Platform for Spin-Selective Quantum Dots in Next-Generation Devices
Maryam Mahdavifar, Farhad Khoeini, Francois M. Peeters
The impact of vacancies on spin-resolved electronic properties of quantum dots (QDs) in phosphorene-based junctions, are investigated numerically. Regardless of the crystal orienta…

Energy levels and Aharonov-Bohm oscillations in twisted bilayer graphene quantum dots and rings
N. S. Bandeira, Andrey Chaves, L. V. de Castro +4
We present a systematic study of the energy levels of twisted bilayer graphene (tBLG) quantum dots (QD) and rings (QR) under an external perpendicular magnetic field. The confineme…
