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.'

Non Equilibrium Green's Functions for Dummies: Introduction to the One Particle NEGF equations
30 Oct 2006 | | Contributor(s):: Magnus Paulsson
Non equilibrium Green's function methods are regularly used to calculate current and charge densities in nanoscale (both molecular and semiconductor) conductors under bias. This method is mainly used for ballistic conduction but may be extended to include inelastic scattering. In this tutorial...
Why is Nanotechnology Multidisciplinary? A perspective of one EE
19 Oct 2006 | | Contributor(s):: Gerhard Klimeck
The field of nano science and nano-technology covers broad areas of expertise. Classical fields of Physics, Chemistry, Material Science, Electrical/Mechanical/Chemical Engineering all are involved in the "new" field. Nano research and development is therefore multidisciplinary. This presentation...
Modeling Quantum Transport in Nanoscale Transistors
30 Oct 2006 | | Contributor(s):: ramesh venugopal
As critical transistor dimensions scale below the 100 nm (nanoscale) regime, quan- tum mechanical effects begin to manifest themselves and affect important device performance metrics. Therefore, simulation tools which can be applied to design nanoscale transistors in the future, require new...

Electrical Resistance: an Atomistic View
26 Oct 2006 | | Contributor(s):: Supriyo Datta
This tutorial article presents a “bottom-up” view of electrical resistance starting from something really small, like a molecule, and then discussing the issues that arise as we move to bigger conductors. Remark ably enough, no serious quantum mechanics is needed to understand electrical...
Nanoscale MOSFETs: Physics, Simulation and Design
