Dataset for Optical characterization of magnesium incorporation in p-GaN layers for core–shell nanorod light-emitting diodes

This dataset contains the results of scanning electron microscopy (SEM), micro-photoluminescence (PL), cathodoluminescence (CL), Raman, and Electron Beam Induced Current (EBIC) measurements carried out on GaN-based core-shell nanostructures. The samples are highly regular arrays of GaN etched cores onto which various p-doped layers were grown using metal organic vapour phase epitaxy (MOVPE). The level of p-doping was varied between different samples.
