摘要： Manufacturers encounter limitations in forming low resistance ohmic electrical contact to semiconductor material P-type Gallium Nitride (p-GaN), commonly used in photonic applications, such that the contact is highly transparent to the light emission of the device. Carbon nanotubes (CNTs) can address this problem due to their combined metallic and semiconducting characteristics in conjunction with the fact that a fabric of CNTs has high optical transparency. The physical structure of the contact scheme is broken down into three components, a) the GaN, b) an interface material and c) the metallic conductor. The role of the interface material is to make suitable contact to both the GaN and the metal so that the GaN, in turn, will make good electrical contact to the metallic conductor that interfaces the device to external circuitry. A method of fabricating contact to GaN using CNTs and metal while maintaining protection of the GaN surface is provided.

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.
