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.

Notes on Scattering and Mobility in 1D, 2D, and 3D
06 Nov 2009 | | Contributor(s):: Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) orquantum confined (2D and 1D) semiconductor structures. Analytical estimates are madethat show the mobility in quantum confined structures is, in general, lower or no higherthan in non-confined ones.

23 Feb 2009 | | Contributor(s):: SungGeun Kim, Benjamin P Haley, Mathieu Luisier, Saumitra Raj Mehrotra, Gerhard Klimeck
This is the first-time user guide for OMEN Nanowire. In addition to showing how the tool operates, it briefly explains what the OMEN Nanowire is, what it can do, and the input and output relationship.NCN@Purdue Sung Dae Suk, et. al., IEDM, 2005, "High Performance 5nm radius Twin Silicon...
Can we define unique effective masses in Si nanowires?
out of 5 stars
06 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise teaches the users that for small nanostructures the concept of the effective mass becomes vague and in order to properly describe nanostructures one has to take into account the numerically calculated dispersion relation. This is clearly illustrated on the example of Si nanowires...
