Micropatterning by non-densely packed interfacial colloidal crystals

Li Jia, The University of Akron


A new surface-patterning method that involves the intact transferring of interfacial non-densely packed hexagonal colloidal crystals onto silicon wafer substrates has been developed. The arrays have long-range order on the square millimeter scale. The laser diffraction pattern of a micropatterned surface is shown in the figure.
