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…
Electrical dipole on gapped graphene: Bound states and atomic collapse
R. Van Pottelberge, B. Van Duppen, F. M. Peeters
We investigate the energy spectrum, wave functions, and local density of states of an electrical dipole placed on a sheet of gapped graphene as function of the charge strength Zα f…
Confined states in graphene quantum blisters
Hasan M. Abdullah, H. Bahlouli, F. M. Peeters +1
Bilayer graphene samples may exhibit regions where the two layers are locally delaminated forming a so-called quantum blister in the graphene sheet. Electron and hole states can be…
Graphene quantum blisters: a tunable system to confine charge carriers
Hasan M. Abdullah, M. Van der Donck, H. Bahlouli +2
Due to Klein tunneling, electrostatic confinement of electrons in graphene is not possible. This hinders the use of graphene for quantum dot applications. Only through quasi-bound…
Graphene membrane as a pressure gauge
S. P. Milovanovic, M. Z. Tadic, F. M. Peeters
Straining graphene results in the appearance of a pseudo-magnetic field which alters its local electronic properties. Applying a pressure difference between the two sides of the me…
Quantum transport in graphene Hall bars: Effects of side gates
M. D. Petrović, F. M. Peeters
Quantum electron transport in side-gated graphene Hall bars is investigated in the presence of quantizing external magnetic fields. The asymmetric potential of four side-gates dist…
