FE-SEM surface images and distribution of relative amounts of NPs in the samples. Representative FE-SEM images of a thin 10-nm metal film on (0001) 4H-SiC after annealing at 500°C for 20 min: (a) Au NPs and (b) Ag NPs. Distribution of the NPs' diameter in relative samples measured from the FE-SEM images: (c) Au NPs and (d) Ag NPs.
