3. 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. Nanoelectronic Modeling Lecture 24: NEMO1D - Incoherent Scattering

   09 Mar 2010 | | Contributor(s):: Gerhard Klimeck

   Incoherent processes due to phonons, interface roughness and disorder had been suspected to be the primary source of the valley current of resonant tunneling diodes (RTDs) at the beginning of the NEMO1D project in 1994. The modeling tool NEMO was created at Texas Instruments to fundamentally...

    23 Sep 2008 | | Contributor(s):: raseong kim, Xufeng Wang, 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...

17. Lecture 7: Connection to the Bottom Up Approach

    out of 5 stars 

    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.

18. Lecture 1A: What and where is the resistance?

    out of 5 stars 

    20 Aug 2008 | | Contributor(s):: Supriyo Datta

    Objective: To introduce a simple quantitative model that highlights the essential parameters that determine electrical conduction: the density of states in the channel, D and the rates at which electrons hop in and out of the two contacts, labeled source and drain. This model is used to explain...
