100 amps of electricity crackle in a vacuum chamber, creating a
spark that transforms carbon vapor into tiny structures. Depending
on the conditions, these structures can be shaped like little,
60-atom soccer balls, or like rolled-up tubes of atoms, arranged
in a chicken-wire pattern, with rounded ends. These tiny, carbon
nanotubes, discovered by Sumio Iijima at NEC labs in 1991, have
amazing properties. They are 100 times stronger than steel, but
weigh only one-sixth as much. They are incredibly resilient
under physical stress; even when kinked to a 120-degree angle,
they will bounce back to their original form, undamaged. And
they can carry electrical current at levels that would vaporize
ordinary copper wires.

Journey Along the Carbon Road
19 Apr 2012 | | Contributor(s):: Zhihong Chen
I will discuss two distinct topics: In the first part of my talk I will present results on carbon nanotubes focusing on high performance computing with the aim to replace silicon in logic device applications. Specifically, the ballistic transport regime that has been reached with the shortest...
Logic Devices and Circuits on Carbon Nanotubes
out of 5 stars
05 Apr 2006 | | Contributor(s):: Joerg Appenzeller
Over the last years carbon nanotubes (CNs) have attracted an increasing interest as building blocks for nano-electronics applications. Due to their unique properties enabling e.g. ballistic transport at room-temperature over several hundred nanometers, high performance CN field-effect...

Mini-Workshop on Carbon-Nanotube FETs
13 May 2003 |
This informal one-day workshop was intended to discuss theory, modeling, and simulation for CNT-electronics, specifically FETs. The objective was to kick off an NSF-funded project on the modeling and simulatin of CNT-electronics. A small group of experimentalists, theorists, and computational...

19 Nov 2012 | | Contributor(s):: Jeremy M Gernand, Elizabeth Casman
This document contains model learning statistics, and structure of the models utilized in the paper “A meta-analysis of carbon nanotube pulmonary toxicity studies – How physical dimensions and impurities affect the toxicity of carbon nanotubes.” This information is meant to supplement and...
Modern X-ray Scattering Methods for Nanoscale Materials Analysis
15 Oct 2008 | | Contributor(s):: Richard J. Matyi
Since its discovery by von Laue in 1912, X-ray diffraction has become an indispensable tool for structure determinations in the physical and biological sciences. X-rays are characterized by high energies and by wavelengths that are commensurate with nanometer-sized structures – unlike optical...

Molecular Dynamics Studies of Gaseous Transport
05 Apr 2006 | | Contributor(s):: Ki-Ho Lee, Jason, Susan Sinnott
Carbon nanotubes (CNTs) have generated a great deal of interest due to their unique properties. In this study, we examine the transport properties of various nanotubes using REBO-MD to determine the effects of diameter and chirality on transport mode. Both oxygen and methane were diffused...
Moore's Law Forever?
13 Jul 2005 | | Contributor(s):: Mark Lundstrom
This talk covers the big technological changes in the 20th and 21st century that were correctly predicted by Gordon Moore in 1965. Moore's Law states that the number of transistors on a silicon chip doubles every technology generation. In 1960s terms that meant every 12 months and currently this...
MOSCNT: code for carbon nanotube transistor simulation
14 Nov 2006 | | Contributor(s):: Siyu Koswatta, Jing Guo, Dmitri Nikonov
Ballistic transport in carbon nanotube metal-oxide-semiconductor field-effect transistors (CNT-MOSFETs) is simulated using the Non-equilibrium Green’s function formalism. A cylindrical transistor geometry with wrapped-around gate and doped source/drain regions are assumed. It should be noted...

Multi-Scale Modeling of Metal-CNT Interfaces
26 Oct 2015 | | Contributor(s):: Martin Claus
IWCE 2015 presentation. the authors studied the impact of contact materials on cntfet behavior using multiscale modeling and simulation framework. a strong correlation between metal-cnt coupling strength, contact length and contact resistance was found. the atomistic simulation was used to...
Multiple Transfers of Single-Walled Carbon Nanotubes on Silicon Wafers
18 Mar 2009 | | Contributor(s):: Alan Salvador Teran
Single-walled carbon nanotubes (SWCNTs) have many applications, including high speed transistor devices (see Figure 1). SWCNTs are grown on single-crystal quartz wafers and then transferred onto silicon wafers by a process that involves gold evaporation and thermal release tape. When they are...
