Low ensemble disorder in quantum well tube nanowires

Abstract:

We have observed very low disorder in high quality quantum well tubes (QWT) in GaAs-Al0.4Ga0.6As core-multishell nanowires. Room-temperature photoluminescence spectra were measured from 150 single nanowires enabling a full statistical analysis of both intra- and inter-nanowire disorder. By modelling individual nanowire spectra, we assigned a quantum well tube thickness, a core disorder parameter and a QWT disorder parameter to each nanowire. A strong correlation was observed between disorder ...
