Nanorod core–shell architecture. (a) Schematic of core–shell structures employed in this work (not to scale), with n-AlGaN cores, quantum wells, and p-AlGaN shells forming a full LED structure. (b) Frequently discussed crystal planes relating to our rods, which also identify the orientation of our TEM lamellae. (c) SE image of the nanorod array with clear uniformity in pitch and rod dimensions. Scale bar is 1 μm. A higher magnification inset (with a 250 nm scale bar) shows a spherical feature at the tip of a rod.
