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…
