Scaling Law in Carbon Nanotube Electromechanical Devices

Nano-electromechanical Devices Robust Carbon-Nanotube-Based Nano-electromechanical Devices: Understanding and Eliminating Prevalent Failure Modes Using Alternative Electrode Materials

The International Technology Roadmap for Semiconductors (ITRS [ 1 ] ) identifi es emerging technologies with the potential to sustain Moore’s Law. A necessary succession from planar CMOS (complementary metal-oxide semiconductors) to nonplanar/dual-gate CMOS, and ultimately to novel architectures such as carbon nanotube (CNT)-based nano-electromechanical systems (NEMS) is envisioned. The ITRS al...

Carbon nanotube junctions and devices Carbon nanotube junctions and devices

Carbon nanotubes are molecules entirely made of carbon atoms. Owing to their special shape, they are extremely stiff but also very flexible. The electronic properties are determined by the exact symmetry of the nanotube lattice, resulting in either metallic or semiconducting behavior. Due to their small diameter, electronic motion is directed in the length direction of the nanotube, making them...

Integration of suspended carbon nanotube arrays into electronic devices and electromechanical systems

A synthetic strategy is devised for reliable integration of long suspended single-walled carbon nanotubes into electrically addressable devices. The method involves patterned growth of nanotubes to bridge predefined molybdenum electrodes, and is versatile in yielding various microstructures comprised of suspended nanotubes that are electrically wired up. The approach affords single-walled nanot...

Mechanical and electromechanical coupling in carbon nanotube distortions

A simple approach is presented for using bond-stretching and bond-bending modes to describe the static deformations of carbon nanotubes and related actuation effects. This approach allows us to analyze various phenomena in a unified way and to clarify their relationships. We discuss gap energy modulation by external strains, dimensional and torsional deformations caused by charge injection, and...
