Atomistic Material Science
03 Nov 2011 | | Contributor(s):: Alejandro Strachan
This course introduces first principles electronic structure calculations of materials properties and the concept of molecular dynamics (MD) simulations of materials focusing on the physics and approximations underlying the simulations and interpretation of their results.
Tutorial 1: Atomistic Material Science - ab initio simulations of materials
This lecture introduces first principles electronic structure calculations of materials properties.It describes the approximations made to the many-body Schrodinger equation in Hartree Fock and Density Functional Theory and numerical approximations used in computer simulations.
Tutorial 2: Atomistic Material Science - Molecular Dynamics simulations of materials
This lecture introduces the concept of molecular dynamics (MD) simulations of materials focusing on the physics and approximations underlying the simulations and interpretation of their results.
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.
Solar Cells Lecture 5: Organic Photovoltaics
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...
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.
Thermal Transport Across Interfaces
23 Aug 2011 | | Contributor(s):: Timothy S Fisher
These lectures provide a theoretical development of the transport ofthermal energy by conduction in nanomaterials, in which materialinterfaces typically dominate transport. The physical nature of energytransport by two carriers: electrons and phonons--will be explored.

Lecture 10: Case study-Near-equilibrium Transport in Graphene
19 Aug 2011 | | Contributor(s):: Mark Lundstrom
Near-equilibrium transport in graphene as an example of how to apply the concepts in lectures 1-8.
Solar Cells Lecture 1: Introduction to Photovoltaics
An introduction to solar cells covering the basics of PN junctions, optical absorption, and IV characteristics. Key technology options and economic considers are briefly presented.
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...
Solar Cells Lecture 2: Physics of Crystalline Solar Cells
Solar cell performance is determined by generation and recombination of electron-hole pairs. This tutorial focussing on recombination losses in crystalline silicon solar cells under short-circuit and open-circuit conditions.
Lecture 7: The Boltzmann Transport Equation
17 Aug 2011 | | Contributor(s):: Mark Lundstrom
Semi-classical carrier transport is traditionally described by the Boltzmann Transport Equation (BTE). In this lecture, we present theBTE, show how it is solved, and relate it to the Landauer Approach usedin these lectures
Lecture 9: Introduction to Phonon Transport
This lecture is an introduction to phonon transport. Key similarities and differences between electron and phonon transport are discussed.
Lecture 5: Thermoelectric Effects - Mathematics
16 Aug 2011 | | Contributor(s):: Mark Lundstrom
Beginning with the general model for transport, we mathematically deriveexpressions for the four thermoelectric transport coefficients:(i) Electrical conductivity,(ii) Seebeck coefficient (or "thermopower"),(iii) Peltier coefficient,(iv) Electronic heat conductivity.
Lecture 6: An Introduction to Scattering
In this lecture, we show how the mean-free-path (mfp) is related to thetime between scattering events and briefly discuss how the scattering time is related to underlying physical processes.
Lecture 8: Measurements
A brief introduction to commonly-used techniques, such as van der Pauw and Hall effect measurements.
