摘要： Under one aspect, a nanotube diode includes: a cathode formed of a semiconductor material; and an anode formed of nanotubes. The cathode and anode are in fixed and direct physical contact, and are constructed and arranged such that sufficient electrical stimulus applied to the cathode and the anode creates a conductive pathway between the cathode and the anode. In some embodiments, the anode includes a non-woven nanotube fabric having a plurality of unaligned nanotubes. The non-woven nanotube fabric may have a thickness, e.g., of 0.5 to 20 nm. Or, the non-woven nanotube fabric may include a block of nanotubes. The nanotubes may include metallic nanotubes and semiconducting nanotubes, and the cathode may include an n-type semiconductor material. A Schottky barrier can form between the n-type semiconductor material and the metallic nanotubes and/or a PN junction can form between the n-type semiconductor material and the semiconducting nanotubes.

摘要： Nanotube ESD protective devices and corresponding nonvolatile and volatile nanotube switches. An electrostatic discharge (ESD) protection circuit for protecting a protected circuit is coupled to an input pad. The ESD circuit includes a nanotube switch electrically having a control. The switch is coupled to the protected circuit and to a discharge path. The nanotube switch is controllable, in response to electrical stimulation of the control, between a de-activated state and an activated state. The activated state creates a current path so that a signal on the input pad flows to the discharge path to cause the signal at the input pad to remain within a predefined operable range for the protected circuit. The nanotube switch, the input pad, and the protected circuit may be on a semiconductor chip. The nanotube switch may be on a chip carrier. The deactivated and activated states may be volatile or non-volatile depending on the embodiment. The ESD circuit may be repeatedly programmed between the activated and deactivated states so as to repeatedly activate and deactivate ESD protection of the protected circuit. The nanotube switch provides protection based on the magnitude of the signal on the input pad.

Such memory cells include a substrate having transistor with a contact that electrically contacts with the transistor. A first support layer is formed over the substrate with an opening that defines a lower chamber above the electrical contact. A nanotube crossbar element is arranged to span the lower chamber. A second support layer is formed with an opening that defines a top chamber above the lower chamber, the top chamber including an extension region that extends beyond an edge of the lower chamber to expose a portion of the top surface of the first support layer. A roof layer covers the top of the top chamber and includes an aperture that exposes a portion of the extension region of the top chamber and includes a plug that extends into the aperture in the roof layer to seal the top and bottom chambers. The memory cell further includes an electrode that overlies the crossbar element such that electrical signals can activate the electrode to attract or repel the crossbar element to set a memory state for the transistor.
