Single-Walled Nanotube (SWNT) crossbar array Molecular Computing
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 forcesStructure and Principle of Operation
