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.'

Process Variation: An Evalution of Carbon Nanotube Transistor Field Effect Transistors
out of 5 stars
16 Aug 2004 | | Contributor(s):: , ,
Process variation is the observed deviation of device parameters in mass production processes. As the critical dimensions of today's MOSFET's are continously decreasing, process variation is becoming an increased problem.
Modification of Si(111) Surfaces using Self - Assembled Monolayers (SAMs) for Electrochemical and AF
16 Aug 2004 |
Recent researchers in the electrical engineering field are using self-assembled monolayers techniques with aryldiazonium salts solutions to build nanoelectronic devices. This innovation can explain the molecular conductivity and the chemical covalent bonds between π- conjugated orbitals of the...
Hydrodynamic Separation of Micron-sized Particles through Magnetization
Many assays and lab-on-a-chip projects require the use of uniform magnetic particles. Creating magnetic particles of uniform size and magnetization is a difficult task. The next best alternative is to make a distribution of particles and separate them.
Visualization of CNT FET Electrical Field Lines
15 Aug 2004 | | Contributor(s):: ,
With transistors decreasing to nanometric dimensions, limits of current processing technologies are being reached. Many physical obstacles still need to be overcome to replace earlier silicon devices with Carbon NanoTube Field Effect Transistors (CNT FETs).
Quantum Dots Visualization Software using Electron Wave Function
15 Aug 2004 | | Contributor(s):: Patrick Macnamara,
The viewing of electron orbitals is a necessary element in the investigation of quantum dot structures as well as in their conceptualization. With an electron wave function superimposed over a crystalline quantum dot structure containing a million to three million atoms, we adapted the marching...
Visualization of and Educational Tool for Quantum Dots
15 Aug 2004 | | Contributor(s):: Aaron Christensen, Adrian Rios
Quantum dots (QDs) are confined structures made of metals and semiconductors that are capable of containing free electrons.The ability to visualize these small devices is advantageous in determining probable electron orbitals and in observing information not easily conceived in raw datasets.
Measurements of Interface Trap Density in MOS Capacitors Using AC Conductance Method
15 Aug 2004 | | Contributor(s):: Benafsha Shahlori
4-H SiC MOS capacitors have a broad interface state density located at approximately 2.9eV above the valence band edge. These states reduce mobility through carrier trapping which in turn affects the electrical performance of these devices. The ac conductance technique is used to measure...
Feasibility of Molecular Assemblers

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...
