In solid-state physics, the electronic band structure of a solid describes ranges of energy that an electron is "forbidden" or "allowed" to have. It is a function of the diffraction of the quantum mechanical electron waves in the periodic crystal lattice with a specific crystal system and Bravais lattice. The band structure of a material determines several characteristics, in particular its electronic and optical properties. More information on Band structure can be found here.
Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
out of 5 stars
08 Jan 2007 | | Contributor(s):: Daniel Neuhauser
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...

This tool simulates E-k and DOS of CNTs and graphene nanoribbons.
Device Physics and Simulation of Silicon Nanowire Transistors
28 Sep 2006 | | Contributor(s):: Jing Wang
As the conventional silicon metal-oxide-semiconductor field-effect transistor (MOSFET) approaches its scaling limits, many novel device structures are being extensively explored. Among them, the silicon nanowire transistor (SNWT) has attracted broad attention from both the semiconductor industry...

Bandstructure in Nanoelectronics
01 Nov 2005 | | Contributor(s):: Gerhard Klimeck
This presentation will highlight, for nanoelectronic device examples, how the effective mass approximation breaks down and why the quantum mechanical nature of the atomically resolved material needs to be included in the device modeling. Atomistic bandstructure effects in resonant tunneling...

MATLAB Scripts for "Quantum Transport: Atom to Transistor"
15 Mar 2005 | | Contributor(s):: Supriyo Datta
Tinker with quantum transport models! Download the MATLAB scripts used to demonstrate the physics described in Supriyo Datta's book Quantum Transport: Atom to Transistor. These simple models are less than a page of code, and yet they reproduce much of the fundamental physics observed in...
Electronic Transport Through Self-Assembled Monolayers
25 Feb 2004 | | Contributor(s):: Takhee Lee
Characterization of charge transport in molecular scale electronic devices has to date shown exquisite sensitivity to specifics of device fabrication and preparation. Thus, intrinsic molecular band structure has been problematic to extract from published results. Here we demonstrate...
