Hierarchy selection, position control, and orientation of growing mesostructures by patterned surfaces
Spontaneous hierarchical organization of silica by means of a patterned surface is described, in which the usual coexistence of energetically similar structures is overcome. A patterned substrate is shown to lead to pixel-like, simultaneous growth of a hierarchal assembly involving four structural levels. The individual pixels belong to a new class of circularly organized solids (see figure and cover).
