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
out of 5 stars
24 Nov 2003 | | Contributor(s):: Craig S. Lent
The multiple challenges presented by the problem of scaling transistor sizes are all related to the fact that transistors encode binary information by the state of a current switch. What is required is a new paradigm, still capable of providing general purpose digital computation, but which can...
Towards a Terahertz Solid State Bloch Oscillator
29 Jan 2004 | | Contributor(s):: S. James Allen
The concepts of Bloch oscillation and Zener breakdown are fundamental to electron motion in periodic potentials and were described in the earliest theoretical developments of electron transport in solids. But only in the past 10 years have experiments clearly demonstrated various aspects of Bloch...
Inelastic Effects in Molecular Conduction
12 Apr 2004 | | Contributor(s):: Abraham Nitzan
Molecular electron transfer, as treated by the Marcus theory, strongly depends on nuclear motion as a way to achieve critical configurations in which charge rearrangement is possible. The electron tunneling process itself is assumed to occur in a static nuclear environment. In the application of...
Electrical Conduction through Molecules
08 Jul 2003 | | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes as well as...
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...
Resistance of a Molecule
29 Apr 2003 | | Contributor(s):: Magnus Paulsson, Ferdows Zahid, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes [1, 2] as well as...
Theory of Ballistic Nanotransistors
27 Nov 2002 | | Contributor(s):: Anisur Rahman, Jing Guo, Supriyo Datta, Mark Lundstrom
Numerical simulations are used to guide the development of a simple analytical theory for ballistic field-effect transistors. When two-dimensional electrostatic effects are small, (and when the insulator capacitance is much less than the semiconductor (quantum) capacitance), the model reduces to...
