Abstract

We have studied nanowires with a GaAs core, covered by an AlGaAs shell, using low temperature cathodoluminescence. The main emission from the core is due carbon acceptors, though we observe a weak emission from excitons. A general observation is that the emission is much stronger from the top half of the nanowire. This emission is also more well-defined. The AlGaAs shell emission varies in emission energy and spatial origin in an irregular fashion.
