Effects of field modulation on Aharonov-Bohm cages in a two-dimensional bipartite periodic lattice
Gi-Yeong Oh
We study the effects of field modulation on the energy spectrum of an electron in a two-dimensional bipartite periodic lattice subject to a magnetic field. Dependence of the energy…
Peierls substitution in the energy dispersion of a hexagonal lattice
Gi-Yeong Oh
The method of the Peierls substitution in studying the magnetic subband structure of a hexagonal lattice is re-examined. Several errors in the formalism of a couple of recent paper…
Magnetic subband structure of an electron on a triangular lattice
Gi-Yeong Oh
The effects of anisotropic nearest-neighbor (NN) and isotropic next-nearest-neighbor (NNN) hopping integrals on the magnetic subband structure of an electron on a triangular lattic…
Aperiodicity-induced effects on the transmission resonances in multibarrier systems
Gi-Yeong Oh
We study the resonant tunneling properties of an electron through a few types of binary periodic and aperiodic multibarrier systems. Within the framework of the effective-mass appr…
Effects of the field modulation on the Hofstadter's spectrum
Gi-Yeong Oh
We study the effect of spatially modulated magnetic fields on the energy spectrum of a two-dimensional (2D) Bloch electron. Taking into account four kinds of modulated fields and u…
Electronic and dynamic properties of a one-dimensional Thue-Morse chain
Gi-Yeong Oh
We study the electronic and dynamic properties of a one-dimensional Thue-Morse chain within the framework of the transfer model. By means of direct diagonalization of the Hamiltoni…
