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.
Metal Oxide Nanowires as Gas Sensing Elements: from Basic Research to Real World Applications
out of 5 stars
21 Sep 2009 | | Contributor(s):: andrei kolmakov
Quasi 1-D metal oxide single crystal chemiresistors are close to occupy their specific niche in the real world of solid state sensorics. Potentially, the major advantage of this kind of sensors with respect to available granular thin film sensors will be their size and stable, reproducible and...

ECE 539 Report: Study of two-dimensional Shrodinger-Poisson Solver
14 May 2009 | | Contributor(s):: Fawad Hassan
We solve the 2-Dimensional Shrodinger-Poisson system of equations using a self consistent scheme (like Gummel Iteration). We study a double gate Silicon Mosfet oriented in the 100 direction using the above setup. We assume a simple 6-valley bandstructure for Silicon.
