Spectra of dark and bright excitons in alloyed nanowire quantum dots

Phys. Rev. B 100, 045309 (2019)

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.
