Molecular collapse in monolayer graphene
Robbe Van Pottelberge, Dean Moldovan, S. P. Milovanovic +1
Atomic collapse is a phenomenon inherent to relativistic quantum mechanics where electron states dive in the positron continuum for highly charged nuclei. This phenomenon was recen…
Magnetic field dependence of the atomic collapse state in graphene
Dean Moldovan, Massoud Ramezani Masir, Francois M. Peeters
Quantum electrodynamics predicts that heavy atoms () will undergo the process of atomic collapse where electrons sink into the positron continuum and a new fam…
Electronic properties of bilayer phosphorene quantum dots in the presence of perpendicular electric and magnetic fields
L. L. Li, D. Moldovan, W. Xu +1
Using the tight-binding approach, we investigate the electronic properties of bilayer phosphorene (BLP) quantum dots (QDs) in the presence of perpendicular electric and magnetic fi…
Tuning a Circular p-n Junction in Graphene from Quantum Confinement to Optical Guiding
Yuhang Jiang, Jinhai Mao, Dean Moldovan +6
The motion of massless Dirac-electrons in graphene mimics the propagation of photons. This makes it possible to control the charge-carriers with components based on geometrical-opt…
Electric- and magnetic-field dependence of the electronic and optical properties of phosphorene quantum dots
L. L. Li, D. Moldovan, W. Xu +1
Recently, black phosphorus quantum dots were fabricated experimentally. Motivated by these experiments, we theoretically investigate the electronic and optical properties of rectan…
Veselago lensing in graphene with a p-n junction: classical versus quantum effects
S. P. Milovanovic, D. Moldovan, F. M. Peeters
The feasibility of Veselago lensing in graphene with a p-n junction is investigated numerically for realistic injection leads. Two different set-ups with two narrow leads are consi…
