  1. 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...

  2. Spin Transport and Topological Insulators I

    29 Aug 2011 | | Contributor(s):: Supriyo Datta

    A major development of the last two decades, the physical and conceptual integration of what used to be two distinct unrelated fields, namely spintronics and magnetics.

  4. Tutorial 1: Thermal Transport Across Interfaces - Phonons

    15 Aug 2011 | | Contributor(s):: Timothy S Fisher

    Outline:Lattice vibrations and phononsThe vibrating stringInterfaces between dissimilar strings: acousticmismatchDiscrete masses and the vibrational eigenspectrumGeneral thermal transport theory

  5. Tutorial 2: A Bottom-Up View of Heat Transfer in Nanomaterials

    23 Mar 2011 | | Contributor(s):: Timothy S Fisher

    This lecture provides a theoretical development of the transport of thermal energy by conduction in nanomaterials. The physical nature of energy transport by two carriers—electrons and phonons--will be explored from basic principles using a common Landauer framework. Issues including the quantum...
