Switches having an in situ grown carbon nanotube as an element thereof, and methods of fabricating such switches. A carbon nanotube is grown in situ in mechanical connection with a conductive substrate, such as a heavily doped silicon wafer or an SOI wafer. The carbon nanotube is electrically connected at one location to a terminal. At another location of the carbon nanotube there is situated a pull electrode that can be used to elecrostatically displace the carbon nanotube so that it selectively makes contact with either the pull electrode or with a contact electrode. Connection to the pull electrode is sufficient to operate the device as a simple switch, while connection to a contact electrode is useful to operate the device in a manner analogous to a relay. In various embodiments, the devices disclosed are useful as at least switches for various signals, multi-state memory, computational devices, and multiplexers.

A method of making a microfluidic device is provided. The method features patterning a permeable wall on a substrate, and surrounding the permeable wall with a solid, non-permeable boundary structure to establish a microfluidic channel having a cross-sectional dimension less than 5,000 microns and a cross-sectional area at least partially filled with the permeable wall so that fluid flowing through the microfluidic channel at least partially passes through the permeable wall.

Devices and methods for performing a procedure within a spine are disclosed herein. In one embodiment, a method includes expanding an expandable member to move a tissue portion and form a cavity within an interior of a bone-related structure. At least a portion of the cavity is filled with a filler material while simultaneously withdrawing a medium from the expandable member at a predefined ratio such that the tissue portion substantially maintains its moved position. In some embodiments, the predefined ratio is 1:1. In another embodiment, a method includes expanding an expandable member to move a tissue portion and form a cavity within an interior of an intervertebral disc. At least a portion of the cavity is filled with a filler material while substantially maintaining the moved position of the tissue portion.

Described is a Schottky diode using semi-conducting single-walled nanotubes (s-SWNTs) with titanium Schottky and platinum Ohmic contacts for high-frequency applications. The diodes are fabricated using angled evaporation of dissimilar metal contacts over an s-SWNT. The devices demonstrate rectifying behavior with large reverse-bias breakdown voltages of greater than −15 V. In order to decrease the series resistance, multiple SWNTs are grown in parallel in a single device, and the metallic tubes are burnt-out selectively. At low biases, these diodes showed ideality factors in the range of 1.5 to 1.9. Modeling of these diodes as direct detectors at room temperature at 2.5 terahertz (THz) frequency indicates noise equivalent powers (NEP) comparable to that of the state-of-the-art gallium arsenide sold-state Schottky diodes, in the range of 10-13 W/square-root (√) Hz.

Techniques are used to fabricate carbon nanotube devices. These techniques improve the selective removal of undesirable nanotubes such as metallic carbon nanotubes while leaving desirable nanotubes such as semiconducting carbon nanotubes. In a first technique, slot patterning is used to slice or break carbon nanotubes have a greater length than desired. By altering the width and spacing of the slotting, nanotubes have a certain length or greater can be removed. Once the lengths of nanotubes are confined to a certain or expected range, the electrical breakdown approach of removing nanotubes is more effective. In a second technique, a Schottky barrier is created at one electrode (e.g., drain or source). This Schottky barrier helps prevent the inadvertent removal the desirable nanotubes when using the electrical breakdown approach. The first and second techniques can be used individually or in combination with each other.
