Atomic-force micrographs of SAM formed on unpatterned for . Scales: (a) , full scale; (b) , full scale.
Atomic-force micrograph showing domains formed in on surface patterned by nanoimprint lithography. Two views of the same AFM image showing surfaces (denoted by arrows) of (a) raised regions and (b) recessed regions. Scales: , full scale.
Atomic-force micrographs of patterned . (a) Without SAM and (b) after SAM formation for . Scales: , full scale. (Arrows indicate raised regions.)
-polarized FTIR spectra of SAMs on unpatterned and NIL-patterned (reacted with OTS for ). The data for the NIL-patterned sample show that the hydrocarbon chains are densely packed and that most chains are nearly vertically oriented.
Atomic-force micrographs of (a) isolated domains on unpatterned chemically oxidized surface, showing cells within domains. Within a domain the lower (dark) regions correspond to the centers of cells; two cells have been marked by white circles. (b) Continuous domains on patterned chemically oxidized surface, showing aligned cells on raised features of pattern. Scales: /division, /division.
