From: Colloidal crystals by electrospraying polystyrene nanofluids
Top view of large domains of polystyrene nanosphere layer. SEM pictures of a colloidal crystal of 360-nm-diameter polystyrene nanospheres electrosprayed onto a silicon substrate deposited under the conditions described for Figure 6: (a) surface of the crystal showing the several domains and (b) a closer view of the dislocation between domains. Scale bars are 1 μm.
