Nanoscopic wire-based devices and arrays
Electrical devices comprised of nanoscopic wires are described, along with methods of their manufacture and use. The nanoscopic wires can be nanotubes, preferably single-walled carbon nanotubes. They can be arranged in crossbar arrays using chemically patterned surfaces for direction, via chemical vapor deposition. Chemical vapor deposition also can be used to form nanotubes in arrays in the presence of directing electric fields, optionally in combination with self-assembled monolayer patterns. Bistable devices are described.

94 . An article, comprising:
a memory element comprising a plurality of nanoscopic wires crossing a plurality of conductors, the memory element able to rectify signals between the plurality of nanoscopic wires.
95 . An article, comprising:
an array comprising a wire disposed proximate a conductor, the wire and the conductor together defining a memory element able to be switched between at least two readable states, the array free of means addressing the memory element to effect switching of the memory element between the at least two states.
