First-Principles Study of Integer Quantum Hall Transitions in Mesoscopic Samples
Chenggang Zhou, Mona Berciu
We perform first principles numerical simulations to investigate resistance fluctuations in mesoscopic samples, near the transition between consecutive Quantum Hall plateaus. We us…
A Laterally Modulated 2D Electron System in the Extreme Quantum Limit
Sorin Melinte, Mona Berciu, C. Zhou +9
We report on magnetotransport of a two-dimensional electron system (2DES), located 32 nm below the surface, with a surface superlattice gate structure of periodicity 39 nm imposing…
Exchange anisotropy, disorder and frustration in diluted, predominantly ferromagnetic, Heisenberg spin systems
Chenggang Zhou, Malcolm P. Kennett, Xin Wan +2
Motivated by the recent suggestion of anisotropic effective exchange interactions between Mn spins in GaMnAs (arising as a result of spin-orbit coupling), we study thei…
Nanoscale Zeeman localization of charge carriers in diluted magnetic semiconductor-permalloy hybrids
Mona Berciu, Boldizsar Janko
We investigate the possibility of charge carrier localization in magnetic semiconductors due to the presence of a highly inhomogeneous external magnetic field. As an example, we st…
