Confined electron states in two-dimensional HgTe in magnetic field: Quantum-dot versus quantum-ring behavior
Dušan B. Topalović, Vladimir V. Arsoski, Milan Ž. Tadić +1
We investigate the electron states and optical absorption in square- and hexagonal-shaped two-dimensional (2D) HgTe quantum dots and quantum rings in the presence of a perpendicula…
Magnetoelectronic properties of normal and skewed phosphorene nanoribbons
Vladimir V. Arsoski, Marko M. Grujic, Nemanja A. Cukaric +2
The energy spectrum and eigenstates of single-layer black phosphorous nanoribbons in the presence of perpendicular magnetic field and in-plane transverse electric field are investi…
Tunable skewed edges in puckered structures
Marko M. Grujić, Motohiko Ezawa, Milan Ž. Tadić +1
We propose a new type of edges, arising due to the anisotropy inherent in the puckered structure of a honeycomb system such as in phosphorene. Skewed-zigzag and skewed-armchair nan…
Chiral properties of topological-state loops
Marko M. Grujić, Milan Ž. Tadić, François M. Peeters
The angular momentum quantization of chiral gapless modes confined to a circularly shaped interface between two different topological phases is investigated. By examining several d…
Orbital magnetic moments in insulating Dirac systems: Impact on magnetotransport in graphene van der Waals heterostructures
Marko M. Grujić, Milan Ž. Tadić, François M. Peeters
In honeycomb Dirac systems with broken inversion symmetry, orbital magnetic moments coupled to the valley degree of freedom arise due to the topology of the band structure, leading…
Strain and band-mixing effects on the excitonic Aharonov-Bohm effect in In(Ga)As/GaAs ringlike quantum dots
Vladimir V. Arsoski, Milan Ž. Tadić, François M. Peeters
Neutral excitons in strained axially symmetric In(Ga)As/GaAs quantum dots with ringlike shape are investigated. Similar to experimental self-assembled quantum rings, the analyzed q…
Antiferromagnetism in hexagonal graphene structures: Rings vs dots
Marko Grujić, Milan Tadić, François M. Peeters
The mean-field Hubbard model is used to investigate the formation of the antiferromagnetic phase in hexagonal graphene rings with inner zigzag edges. The outer edge of the ring was…
Anticrossing-induced optical excitonic Aharonov-Bohm effect in strained type-I semiconductor nanorings
M. Tadić, N. Čukarić, V. Arsoski +1
The exciton states in strained (In,Ga)As nanorings embedded in a GaAs matrix are computed. The strain distribution is extracted from the continuum mechanical model, and the exact d…
