Abstract
A “minimal-lithography” technique for chemically assembling small deterministic crossbars of single-walled carbon nanotube (SWNT) ropes: The formation of electrically conducting crossbar circuits with 8 to 14 junctions (see picture) from a suspension of SWNTs is described. The critical structural parameters of the circuits were controlled by chemically directed self-assembly, rather than lithographic patterning, and all steps were carried out under ambient conditions.
