Progress in technology has brought microelectronics to the nanoscale, but nanoelectronics is not yet a well-defined engineering discipline with a coherent, experimentally verified, theoretical framework. The NCN has a vision for a new, 'bottom-up' approach to electronics, which involves: understanding electronic conduction at the atomistic level; formulating new simulation techniques; developing a new generation of software tools; and bringing this new understanding and perspective into the classroom. We address problems in atomistic phenomena, quantum transport, percolative transport in inhomogeneous media, reliability, and the connection of nanoelectronics to new problems such as biology, medicine, and energy. We work closely with experimentalists to understand nanoscale phenomena and to explore new device concepts. In the course of this work, we produce open source software tools and educational resources that we share with the community through the nanoHUB.
This page is a starting point for nanoHUB users interested in nanoelectronics. It lists key resources developed by the NCN Nanoelectronics team. The nanoHUB contains many more resources for nanoelectronics, and they can be located with the nanoHUB search function. To find all nanoelectronics resources, search for 'nanoelectronics.' To find those contributed by the NCN nanoelectronics team, search for 'NCNnanoelectronics.'

Quantum-dot Cellular Automata (QCA) - Logic Gates
out of 5 stars
03 Feb 2006 |
An earlier animation described how "Quantum-dot Cellular Automata" (QCAs) could serve as memory cells and wires. This animation contnues the story by describing how QCAs can be made into MAJORITY, OR, AND, and INVERTER logic gates.
A Primer on Semiconductor Device Simulation
23 Jan 2006 | | Contributor(s):: Mark Lundstrom
Computer simulation is now an essential tool for the research and development of semiconductor processes and devices, but to use a simulation tool intelligently, one must know what's "under the hood." This talk is a tutorial introduction designed for someone using semiconductor device simulation...
Optimization of Transistor Design for Carbon Nanotubes
20 Jan 2006 | | Contributor(s):: Jing Guo
We have developed a self-consistent atomistic simulator for CNTFETs.Using the simulator, we show that a recently reported high-performanceCNTFET delivers a near ballistic on-current. The off-state, however, issignificantly degraded because the CNTFET operates like anon-conventional Schottky...
A 3D Quantum Simulation of Silicon Nanowire Field-Effect Transistors
17 Jan 2006 | | Contributor(s):: Mincheol Shin
As the device size of the conventional planar metal oxide semiconductor field effect transistor(MOSFET) shrinks into the deep sub micron regime, the device performance significantly degradesmainly due to the short-channel effect. The silicon nanowire field-effect transistor (SNWFET) isconsidered...

Quantum Corrections for Monte Carlo Simulation
05 Jan 2006 | | Contributor(s):: Umberto Ravaioli
Size quantization is an important effect in modern scaled devices. Due to the cost and limitations of available full quantum approaches, it is appealing to extend semi-classical simulators by adding corrections for size quantization. Monte Carlo particle simulators are good candidates, because a...

Notes on the Ballistic MOSFET
08 Oct 2005 | | Contributor(s):: Mark Lundstrom
When analyzing semiconductor devices, the traditional approach is to assume that carriers scatter frequently from ionized impurities, phonons, surface roughness, etc. so that the average distance between scattering events (the so-called mean-free-path, λ) is much shorter than the device. When...
