  1. Quantum Workshop III: LED Circuit and Device Physics

    07 Feb 2015 | Contributor(s):: Stella Quinones

    A hands-on learning exercise used to illustrate the device physics of a light emitting diode (LED) in a simple resistor circuit.  Students explore the photon energy of four LEDs, compare the voltage drop (or forward bias) across the LED, and explain the behavior of the LED under...

  2. Real space first-principles semiempirical pseudopotentials for Fe/MgO/Fe

    03 Dec 2008 | | Contributor(s):: Kirk Bevan

    A set of semiempirical pseudopotentials for the atomistic modeling of Fe/MgO/Fe tunnel junctions. See the attached document for a full description of their derivation and the modeling approach.Document Abstract:We present a real space density functional theory (DFT) localized basis set...

  8. Solar Cell Fundamentals

    19 Aug 2011 | | Contributor(s):: Mark Lundstrom, J. L. Gray, Muhammad A. Alam

    The modern solar cell was invented at Bell Labs in 1954 and is currently receiving renewed attention as a potential contribution to addressing the world's energy challenge. This set of five tutorials is an introduction to solar cell technology fundamentals. It begins with a broad overview of...

  9. Solar Cells Lecture 4: What is Different about Thin-Film Solar Cells?

    29 Aug 2011 | | Contributor(s):: Muhammad A. Alam

    Thin film solar cells promise acceptable efficiency at low cost. This tutorial examines the device physics of thin-film solar cells, which generally require a different type of analysis than crystalline solar cells.

  10. Solar Cells Lecture 5: Organic Photovoltaics

    29 Aug 2011 | | Contributor(s):: Muhammad A. Alam

    Organic solar cells make use of low-cost organic polymers forphotovoltaics. Although these solar cells may appear to be quitedifferent from solar cells made with conventional, inorganicsemiconductors (e.g. they make use of exciton generation rather than electron-hole generation) this...

  11. Thermoelectric Power Factor Calculator for Nanocrystalline Composites

    18 Oct 2008 | | Contributor(s):: Terence Musho, Greg Walker

    Quantum Simulation of the Seebeck Coefficient and Electrical Conductivity in a 2D Nanocrystalline Composite Structure using Non-Equilibrium Green's Functions

  13. Two-Dimensional Scattering Matrix Simulations of Si MOSFET'S

    27 Jun 2013 | | Contributor(s):: Carl R. Huster

    For many years now, solid state device simulators have been based on the drift-diffusion equations. As transistor sizes have been reduced, there has been considerable concern about the predictive capability of these simulators. This concern has lead to the development of a number of simulation...
