Not Accessible

Your library or personal account may give you access

Abstract

We present optical studies of carrier confinement in GaN/AlN quantum discs in nanowires and their application to photodetection on the nanoscale. Single-nanowire UV photodetector relying on carrier generation in quantum discs is demonstrated.
