Abstract

original image

Colloidal silicon nanocrystal superlattices: Nanocrystal superlattices are finally made of the most commercially relevant semiconductor, silicon. These sterically-stabilized nanocrystals self-assemble into face-centered cubic superlattices (see picture). Their thermal stability is much more robust than other types of nanocrystal superlattices because of the strong covalent bonding of the hydrocarbon capping layer.
