A nanowire is a nanostructure, with the diameter of the order of a nanometer. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important.

What Can the TEM Tell You About Your Nanomaterial?
out of 5 stars
26 Feb 2007 | | Contributor(s):: Eric Stach
In this tutorial, I will present a brief overview of the ways that transmission electron microscopy can be used to characterize nanoscale materials. This tutorial will emphasize what TEM does well, as well where difficulties arise. In particular, I will discuss in an overview manner how...
Atomistic Alloy Disorder in Nanostructures
26 Feb 2007 | | Contributor(s):: Gerhard Klimeck
Electronic structure and quantum transport simulations are typically performed in perfectly ordered semiconductor structures. Bands and modes are defined resulting in quantized conduction and discrete states. But what if the material is fundamentally disordered? What if the disorder is at the...
SPMW Nanomechanics: from nanotechnology to biology

The development of new materials with size of few nanometers has opened a new field of scientific and technological research. The goal is to develop faster and better communication systems and transports, as well as smarter and smaller nanodevices for biomedical applications. To reach these...
Materials strength: does size matter? nanoMATERIALS simulation toolkit tutorial
01 Feb 2007 | | Contributor(s):: Alejandro Strachan
Molecular dynamics (MD) is a powerful technique to characterize the fundamental, atomic-level processes that govern materials behavior and is playing an important role in our understanding of the new phenomena that arises in nanoscale and nanostructured materials and result in their unique...
Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
08 Jan 2007 | | Contributor(s)::
As nanonphotonics and nanoelectronics are pushed down towards the molecular scale, interesting effects emerge. We discuss how birefringence (different propagation of two polarizations) is manifested and could be useful in the future for two systems: coherent plasmonic transport of near-field...
