Carbon Nanotube Quantum Nano Devices

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...

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 quantum resistors

The conductance of multiwalled carbon nanotubes (MWNTs) was found to be quantized. The experimental method involved measuring the conductance of nanotubes by replacing the tip of a scanning probe microscope with a nanotube fiber, which could be lowered into a liquid metal to establish a gentle electrical contact with a nanotube at the tip of the fiber. The conductance of arc-produced MWNTs is o...

The Nano-Memory Devices of a Single Wall and Peapod Structural Carbon Nanotube Field Effect Transistor

The rediscovery and the memory application of single walled carbon nanotubes (SWNTs) give a new method in nanoelectronics applications. At first we will report the memory effects of a SWNT, and attempt to use this property in a memory device. To use a SWNT field effect transistor (FET) as a charge-storage memory device, the device operates by injecting electrons from the nanotube channel of a T...
