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.'

Understanding Molecular Conduction
08 Jul 2004 | | Contributor(s):: Supriyo Datta
It is common to differentiate between two ways of building a nanodevice: a topdown approach where we start from something big and chisel out what we want and abottom-up approach where we start from something small like atoms or molecules andassemble what we want. When it comes to describing...

Exponential Challenges, Exponential Rewards - The Future of Moore's Law
14 Dec 2004 |
Three exponentials have been the foundation of today's electronics, which are often taken for granted—namely transistor density, performance, and energy. Moore's Law captures the impact of these exponentials. Exponentially increasing transistor integration capacity, and exponentially...

Faster Materials versus Nanoscaled Si and SiGe: A Fork in the Roadmap?
20 Apr 2004 | | Contributor(s):: Jerry M. Woodall
Strained Si and SiGe MOSFET technologies face fundamental limits towards the end of this decade when the technology roadmap calls for gate dimensions of 45 nm headed for 22 nm. This fact, and difficulties in developing a suitable high-K dielectric, have stimulated the search for alternatives to...
Control of Exchange Interaction in a Double Dot System
05 Feb 2004 | | Contributor(s):: Mike Stopa
As Rolf Landauer observed in 1960, information is physical. As a consequence, the transport and processing of information must obey the laws of physics. It therefore makes sense to base the laws of information processing and computation on the laws of physics and in particular on quantum...

Nanoelectronics and the Future of Microelectronics
22 Aug 2002 | | Contributor(s):: Mark Lundstrom
Progress in silicon technology continues to outpace the historic pace of Moore's Law, but the end of device scaling now seems to be only 10-15 years away. As a result, there is intense interest in new, molecular-scale devices that might complement a basic silicon platform by providing it...

Recent demonstrations of high performance carbon nanotube field-effect transistors (CNFETs) highlight their potential for a future nanotube-based electronics. Besides being just a nanometer in diameter, carbon nanotubes offer intrinsic advantages if compared with silicon that are responsible for...
Quantum-dot Cellular Automata
