Nanocrystal Self‐Assembly Assisted by Oriented Attachment

Self-assembly with self-control: Fe2O3 nanocrystals underwent self-assembly in a disciplined manner to form one-, two-, and three-dimensional ordered structures by the mechanism of oriented attachment (see picture). Thus, the formation of the organized superstructures did not require external control, for example, by temperature and pressure, but was intrinsic to the nanocrystal system.
