Pyramids formed by 200nm Au film deposited on patterned substrate. Overlay of secondary electron image (grey) and, 650nm (green) and 750nm (red) monochromatic images. Bottom left: Irregularity in emission of GaAs nanowires. In-lens secondary electron image overlaid with panchromatic CL image (green); images acquired simultaneously.Bottom right: Four AlGaN concentrations revealed in graded AlxGa1-xN on GaN film using spectrum-linescan of sample cross section. Blue shift in spectrum from 365 to 320nm associated with change in Al fraction. Spectra acquired at rate of 20 spectra/s.
