Plan-view SEM image and CL emission properties of single micro-LED (a) Plan-view SEM image of single micro-LED grown on sapphire nano-membrane. Monochromatic CL images measured at wavelengths of (b) 375 nm, (c) 387 nm, and (d) 435 nm. (e) Spatially-resolved CL spectra measured at \(\{11\bar{2}2\}\), \(\{1\bar{1}01\}\), and \((0001)\) facets. The inset figure shows the CL spectra in log scale.
