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.

Data collection method:
Secondary electron images were captured using a Hitachi S-4300 scanning electron microscope (SEM). Micro-PL characterization was performed with a He–Cd 325 nm laser excitation source at 0.135 mW power output and a 2400 lines mm−1 diffraction grating in order to obtain a good signal to noise ratio. A 40× magnification, 0.50 numerical aperture (NA) objective produced a spot size of ~0.8 µm, small enough to probe single NRs on a 2 µm pitch. CL maps were obtained on a subset of samples, using an electron beam with a low energy of 2 keV. For the Raman measurements, a high-resolution confocal Raman spectrometer (Renishaw inVia) with a 532 nm laser source, 3000 lines mm−1 grating and 150×, 0.95 NA objective was used. The laser power was 10 mW, the lateral spatial resolution was 0.3 µm and the measurement resolution of the spectral shift was 0.01cm−1. .
