Single-Walled Nanotube (SWNT) crossbar array
Bi-stable electromechanical switch
OFF and ON states corresponding to elastic energy at finite separation and van der Waal energy minima
Switching between the states is accomplished by transiently charging SWNT to produce attractive and repulsive forces
“Organic or Inorganic
van der Waal contact
RON/ROFF ~ 10
RON/ROFF ~ 105
ON/OFF state can be detected by measuring the resistance of the junction
Random distribution of metallic and semiconducting SWNT
Crosspoint structure has multiple pathways and would need directional element like diode
