摘要：
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 to carbon acceptors, though we observe a weak emission from excitons. A general observation is that the emission is much stronger, and more well-defined, from the top half of the nanowire. The AlGaAs shell emission varies in emission energy and spatial origin in an irregular fashion.
