Scientists observe composite superstructure growth from nanocrystals in real time
Artist's impression of spherical binary nanocrystal superlattices featuring semiconductor (emissive) and magnetic/plasmonic (non-emissive) nanocrystals.

A collaborative team of researchers led by PIK Professor Christopher B. Murray has observed for the first time composite superstructure growth from nanocrystals in real time. The discovery could enable engineers to more reliably manufacture next-generation materials by combining different nanocrystals. Shown here is an artist's impression of spherical binary nanocrystal superlattices featuring semiconductor (emissive) and magnetic/plasmonic (non-emissive) nanocrystals.
