Interplay between carrier and impurity concentrations in annealed GaMnAs intrinsic anomalous Hall Effect
S. H. Chun, Y. S. Kim, H. K. Choi +8
Investigating the scaling behavior of annealed GaMnAs anomalous Hall coefficients, we note a universal crossover regime where the scaling behavior changes from quadra…
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 photoluminescence study of InAs/AlGaAs quantum-dot-based nanoclusters: band filling effect
Young-Jun Yu, Han-Eol Noh, Mun-Heon Hong +5
We have performed near-field spectroscopy and microscopy of the InAs/AlGaAs quantum-dot-based nanoclusters. It is observed that the photoluminescence spectra of spatially confined…
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…
