Solar Cells Lecture 5: Organic Photovoltaics
29 Aug 2011 | Online Presentations | Contributor(s): Muhammad A. Alam
Organic solar cells make use of low-cost organic polymers for
photovoltaics. Although these solar cells may appear to be quite
different from solar cells made with conventional,...
Spin Transport and Topological Insulators I
29 Aug 2011 | Online Presentations | 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.
Spin Transport and Topological Insulators II
19 Aug 2011 | Online Presentations | Contributor(s): Supriyo Datta
Lecture 10: Case study-Near-equilibrium Transport in Graphene
19 Aug 2011 | Online Presentations | 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 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...
Lecture 7: The Boltzmann Transport Equation
17 Aug 2011 | Online Presentations | Contributor(s): Mark Lundstrom
Semi-classical carrier transport is traditionally described by the
Boltzmann Transport Equation (BTE). In this lecture, we present the
BTE, show how it is solved, and relate it to the Landauer...
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 | Online Presentations | Contributor(s): Mark Lundstrom
Beginning with the general model for transport, we mathematically derive
expressions for the four thermoelectric transport coefficients:
(i) Electrical conductivity,
(ii) Seebeck coefficient...
Lecture 6: An Introduction to Scattering
In this lecture, we show how the mean-free-path (mfp) is related to the
time 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.
Tutorial 2: Thermal Transport Across Interfaces - Electrons
16 Aug 2011 | Online Presentations | Contributor(s): Timothy S Fisher

Carbon nanotube interfaces
“Electronics from the Bottom Up” is an educational initiative...
Tutorial 1: Thermal Transport Across Interfaces - Phonons
15 Aug 2011 | Online Presentations | Contributor(s): Timothy S Fisher
Lattice vibrations and phonons
The vibrating string
Interfaces between dissimilar strings: acoustic
Discrete masses and the vibrational eigenspectrum
Lecture 2: General Model for Transport
28 Jul 2011 | Online Presentations | Contributor(s): Mark Lundstrom
Datta's model of a nanodevice is introduced as a general way of describing nanodevices as well, as bulk metals and semiconductors.
Lecture 3: Resistance-Ballistic to Diffusive
The resistance of a ballistic conductor and concepts, such as the quantum
contact resistance, are introduced and discussed. The results are then
generalized to treat transport all the way from...
Lecture 4: Thermoelectric Effects-Physical Approach
The effect of temperature gradients on current flow and how electrical currents produce heat currents are discussed.
