Dielectrophoretic reconfiguration of nanowire interconnects

چکیده

Silicon nanowire interconnects are dielectrophoretically assembled, reconfigured, and disassembled between gold electrodes in benzyl alcohol. Assembly of up to 55 μm long nanowires is demonstrated. Conductance enhancement is observed in the presence of single nanowires trapped between submerged electrodes. Phase inversion of electrode potentials allows the reversible reconfiguration of nanowires, either serially or in parallel. For disassembly, high-voltage bursts are observed to detonate trapped nanowires. The reconfiguration of colloidal electronic nanostructures opens up the possibility of nanostructured connection architectures for computation.

5 Dielectrophoretic Architectures

Electric programmability has been the basis for decades of advances in integrated computer component performance. However, once fabricated or assembled, such components—whether blade servers in a data center or microprocessors on a circuit board—are typically stuck in place and require human intervention for reconfiguration, removal, or replacement. For continued advances at the architectural l...

Dielectrophoretically controlled fabrication of single-crystal nickel silicide nanowire interconnects.

We report here on applying electric fields and dielectric media to achieve controlled alignment of single-crystal nickel silicide nanowires between two electrodes. Depending on the concentration of nanowire suspension and the distribution of electrical field, various configurations of nanowire interconnects, such as single, chained, and branched nanowires were aligned between the electrodes. Se...

High-yield self-limiting single-nanowire assembly with dielectrophoresis.

Single-crystal nanowire transistors and other nanowire-based devices could have applications in large-area and flexible electronics if conventional top-down fabrication techniques can be integrated with high-precision bottom-up nanowire assembly. Here, we extend dielectrophoretic nanowire assembly to achieve a 98.5% yield of single nanowires assembled over 16,000 patterned electrode sites with ...

Precise Placement of Metallic Nanowires on a Substrate by Localized Electric Fields and Inter-Nanowire Electrostatic Interaction

Placing nanowires at the predetermined locations on a substrate represents one of the significant hurdles to be tackled for realization of heterogeneous nanowire systems. Here, we demonstrate spatially-controlled assembly of a single nanowire at the photolithographically recessed region at the electrode gap with high integration yield (~90%). Two popular routes, such as protruding electrode tip...

Dielectrophoretic growth of platinum nanowires: concentration and temperature dependence of the growth velocity.

The growth velocity of platinum nanowires in an aqueous solution of K(2)PtCl(4) is investigated as a function of the metal complex concentration and temperature. The solution is specially prepared to provide mainly the neutral complex cis-[PtCl(2)(H(2)O)(2)] for growing nanowires by dielectrophoresis. The measured growth velocities indicate diffusion-limited nanowire growth at low concentration...
