Gı̂rgel, I., Le Boulbar, E., Coulon, P., Sahonta, S., Allsopp, D., Humphreys, C., Shields, P., 2016. Dataset for Investigation of InGaN facet-dependent non-polar growth rates and composition for core-shell LEDs. University of Bath. https://doi.org/10.15125/BATH-00172.


Core-shell InGaN/GaN structures are attractive as light emitters due to their potential for emission on large non-polar surface area and flexibility in achieving different emission wavelengths with changing growth parameters. The morphology and dimensional dependence of InGaN layers with growth parameters were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Growth rates for InGaN under different growth parameters for the non-polar a- and m-planes were determined.

Dataset abstract

This dataset contains the results of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) measurements carried out on core-shell nanostructures. The samples are highly regular arrays of GaN plasma etched cores onto which thick InGaN layers were grown using different metal organic vapour phase epitaxy (MOVPE) growth parameters. Three different InGaN growth conditions were considered with the following parameters: 750°C at 300 mbar, 700°C at 300 mbar and 750°C at 100 mbar. Statistical growth rates were determined on the non-polar crystal planes from measurements of increase in diameter using SEM images. TEM analysis was carried out on a single nanorod for greater detail.
