Abstract
Electro-mechanical switches and memory cells using vertically-oriented nanofabric articles and methods of making the same. Under one aspect, a nanotube device includes a substantially horizontal substrate having a vertically oriented feature; and a nanotube film substantially conforming to a horizontal feature of the substrate and also to at least the vertically oriented feature. Under another aspect, an electromechanical device includes a structure having a major horizontal surface and a channel formed therein, the channel having first and second wall electrodes defining at least a portion of first and second vertical walls of the channel; first and second nanotube articles vertically suspended in the channel and in spaced relation to a corresponding first and second wall electrode, and electromechanically deflectable in a horizontal direction toward or away from the corresponding first and second wall electrode in response to electrical stimulation.
