The NEGF Approach to Nano-Device Simulation
site
The non-equilibrium Greens function (NEGF) formalism provides a powerful conceptual and computational framework for treating quantum transport in nanodevices. It goes beyond the Landauer approach for ballistic, non-interacting electronics to include inelastic scattering and strong...
NCN Nanoelectronics
Microelectronics was one of the great technologies of the 20th century. Progress in technology has now taken microelectronics to the nanoscale, but nanoelectronics is not yet an engineering discipline. The NCN has a vision to re-invent electronics from the “bottom-up,” by which we...
NCN Nanophotonics and Metamaterials
NCN-SLC holds an NCN Student Research Symposium (NSRS) in Spring/ Summer each year. The purpose is to bring together students from the various research groups working on nanoscience and computational disciplines and provide a forum for sharing of ideas and knowledge. NCN Student Research...
NCN Nano Electro-Mechanical Systems
NEMS is an integration of mechanical, electrical, fluidic, optical, chemical, biological and other components. We often think of this integration as occurring on a chip, but self-sensing/actuating probes in Scanning Probe Microscopy instruments are also true nanoelectro-mechanical systems. ...
NCN Nano-Devices for Medicine and Biology
This NCN theme seeks to extend the understanding and computational tools developed in the Nanoelectronics and NEMS themes and apply them to the development of devices for medicine and biology. The long-term vision is to develop a full hierarchy of coupled models and simulations that constitute a...
Electronics from the Bottom Up: A New Approach to Nanoelectronic Devices and Materials
Vision The Network for Computational Nanotechnology seeks to bring a new perspective to engineering education to meet the challenges and opportunities of modern nanotechnology. Fifty years ago our field faced a similar challenge brought on by the advent of the transistor and it was met...
NCN@Purdue Students
Network for Computational Nanotechnology (NCN) is a National Science Foundation (NSF) gateway and research network with a mission to enable education and research in nanoscience for nanotechnology applications. NCN currently focuses on nanoelectronics, nanoelectromechanics, nanomaterials,...
NCN Nanomaterials
Nanomaterials have a structure whose size is on the scale of 1-100nm. Materials with this size characteristic can have unique chemical, electrical, optical, thermal and structural properties. A classic example is the variance of the color of gold particles with respect to particle size. ...
French & American Young Engineering Scientists Symposium 2009
November 16-18, 2009 NOTE: New travel information has been added. Introduction Scientists and engineers from the US and France have been building collaborative linkages between young scientists over the last two years through a series of workshops and symposia sponsored by the U.S. National...
Learning Module: Atomic Picture of Plastic Deformation in Metals
The main goal of this learning module is to introduce students to the atomic-level processes responsible for plastic deformation in crystalline metals and help them develop a more intuitive understanding of how materials work at molecular scales. Image to the right shows plastic deformation of a...

Aluminum-Rich Bulk Alloys: an Energy Storage Material for Splitting Water to Make Hydrogen Gas on Demand
The two major barriers to realizing a viable large-scale hydrogen economy are hydrogen storage and economically viable “green” hydrogen production. The current two preferred methods of hydrogen generation are water electrolysis and the decomposition of natural gas (methane). Even though both...
Resources for Materials Science and Engineering
Ab initio electronic structure simulation tools ABINIT :ABINIT is a package whose main program allows to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory, using...
