This work analyzes how alloy randomness modifies both dark and bright excitons in nanowire quantum dots. It highlights that nominally weak atomistic disorder can strongly affect fine details of excitonic spectra and polarization properties.
Keywords: nanowire quantum dots
Main result: alloy randomness has a pronounced impact on the energies and optical signatures of both bright and dark excitons in nanowire quantum dots. Realistic alloy modeling is therefore essential for quantitative spectroscopy.
