Abstract

Methods and systems of using nanotube elements as joule heating elements for memories and other applications. Under one aspect, a method includesproviding an electrical stimulus, regulated by a drive circuit, through a nanotube element in order to heat an adjacent article. Further, a detection circuit electrically gauges the state of the article. The article heated by the nanotube element is, in preferred embodiments, a phase changing material, hi memory applications, the invention may be used as a small-scale CRAM capable of employing small amounts of current to induce rapid, large temperature changes in a chalcogenide material. Under various embodiments of the disclosed invention, the nanotube element is composed of a non-woven nanotube fabric which is either suspended from supports and positioned adjacent to the phase change material or is disposed on a substrate and in direct contact with the phase change material. A plurality of designs using various geometric orientations of nanotube fabrics, phase change materials, and drive and detection circuitry is disclosed. Additionally, methods of fabricating nanotube heat emitters are disclosed.
