Tree-level electron-photon interactions in graphene
Matthew Mecklenburg, Jason Woo, B. C. Regan
Graphene's low-energy electronic excitations obey a 2+1 dimensional Dirac Hamiltonian. After extending this Hamiltonian to include interactions with a quantized electromagnetic fie…
Evidence of metallic clustering in annealed Ga1-xMnxAs from atypical scaling behavior of the anomalous Hall coefficient
H. K. Choi, W. O. Lee, Y. S. OH +9
We report on the anomalous Hall coefficient and longitudinal resistivity scaling relationships on a series of annealed Ga1-xMnxAs epilayers (x~0.055). As-grown samples exhibit scal…
Near-field spectroscopy of bimodal size distribution of InAs/AlGaAs quantum dots
Young-Jun Yu, I. T. Jeong, J. C. Woo +1
We report on high-resolution photoluminescence (PL) spectroscopy of spatial structure of InAs/AlGaAs quantum dots (QDs) by using a near-field scanning optical microscope (NSOM). Th…
Spin-Landau Orbit Coupling in Units of the Flux Quantum Observed from Zeeman Splitting of a Quantum Wire Array
J. C. Woo, W. S. Kim, H. S. Ko +6
In Zeeman spectra of a GaAs-AlGaAs quantum wire array with superlattice period lp, the zero-field shift is found to increase in steps of (2 pi hbar/ e)lp^{-2} at the cyclotron radi…
