This page gathers publications on self-assembled semiconductor quantum dots, with emphasis on strain, band offsets, excitonic spectra, spin-related properties, and atomistic many-body modeling.
This work shows that atomic-scale alloy randomness alone can activate and reshape dark-exciton optical signatures in nominally symmetric self-assembled quantum dots. It links dark-exciton visibility directly to microscopic alloy configuration.
Keywords: self-assembled quantum dots
Main result: alloy randomness can strongly enhance and modify dark–bright exciton mixing without requiring deliberate faceting or elongation. Dark-exciton properties in alloyed dots are therefore intrinsically sample-specific.
This work analyzes excitonic fine structure and related optical anisotropies with atomistic many-body theory. It focuses on how realistic geometry, composition, and symmetry breaking determine the low-energy excitonic manifold.
Keywords: self-assembled quantum dots, fine-structure splitting
Main result: fine details of excitonic splitting and polarization are controlled by atomistic symmetry, realistic shape, and material inhomogeneity. Simplified continuum expectations are often insufficient at the µeV scale.
