Hofstadter's butterfly in moire superlattices: A fractal quantum Hall effect
C. R. Dean, L. Wang, P. Maher +12
Electrons moving through a spatially periodic lattice potential develop a quantized energy spectrum consisting of discrete Bloch bands. In two dimensions, electrons moving through…

The Effects of Post-Thermal Annealing on the Emission Spectra of GaAs/AlGaAs Quantum Dots grown by Droplet Epitaxy
Pilkyung Moon, J. D. Lee, S. K. Ha +5
We fabricated GaAs/AlGaAs quantum dots by droplet epitaxy method, and obtained the geometries of the dots from scanning transmission electron microscopy data. Post-thermal annealin…

Energy Spectrum and Quantum Hall Effect in Twisted Bilayer Graphene
Pilkyung Moon, Mikito Koshino
We investigate the electronic spectra and quantum Hall effect in twisted bilayer graphenes with various rotation angles under magnetic fields, using a model rigorously including th…
