Probing the trapping and thermal activation dynamics of excitons at single twin defects in GaAs–AlGaAs core–shell nanowires

Time resolved and time-integrated photoluminescence (PL) spectroscopy is used to investigate the trapping and thermal activation dynamics of excitons bound to single twin defects in individual GaAs–AlGaAs core–shell nanowires. The GaAs core exhibits two distinct spectral emission features that are a...
