  1. Lecture 7: Connection to the Bottom Up Approach

    23 Sep 2008 | | Contributor(s):: Mark Lundstrom

    While the previous lectures have been in the spirit of the bottom up approach, they did not follow the generic device model of Datta. In this lecture, the ballistic MOSFET theory will be formally derived from the generic model for a nano-device to show the connection explicitly.

  2. Local density of states

    17 Apr 2010 | | Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck

    The concept of general density of states (DOS) in devices is, by definition, spatially invariant. However, in the case of inhomogeneous materials or in quantum confined structures, the density of states can be resolved in space. This is known as local density of states, or LDOS. …

  4. Notes on Fermi-Dirac Integrals (3rd Edition)

    23 Sep 2008 | | Contributor(s):: raseong kim, Mark Lundstrom

    Fermi-Dirac integrals appear frequently in semiconductor problems, so an understanding of their properties is essential. The purpose of these notes is to collect in one place, some basic information about Fermi-Dirac integrals and their properties. We also present Matlab functions (in a zipped...
