ITO Dopant Distribution (image) DOE/Lawrence Berkeley National Laboratory Caption This is a schematic representation of plasmonic nanocrystals with (a) uniform and (b) surface-segregated dopant distributions. In (a), most of the electron cloud is scattered from ionized impurities (green); in (b), most of the electron cloud is oscillating away from the impurities.
