Lecture 5: NEGF Simulation of Graphene Nanodevices
23 Sep 2009 | | Contributor(s):: Supriyo Datta
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: 3D Nets in a 3D World: Bulk Heterostructure Solar Cells
Outline:Introduction: definitions and review
Reaction diffusion in fractal volumesCarrier transport in BH solar cellsAll phase transitions are not fractalConclusions
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 6: Graphene PN Junctions
22 Sep 2009 | | Contributor(s):: Mark Lundstrom
Outline:IntroductionElectron optics in grapheneTransmission across NP junctionsConductance of PN and NN junctionsDiscussionSummary
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.
Lecture 7: On Reliability and Randomness in Electronic Devices
14 Apr 2010 | | Contributor(s):: Muhammad A. Alam
Outline:Background informationPrinciples of reliability physicsClassification of Electronic ReliabilityStructure Defects in Electronic MaterialsConclusions
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 8: Measurements
A brief introduction to commonly-used techniques, such as van der Pauw and Hall effect measurements.

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.
Lessons from Nanoelectronics
20 Jul 2011 | | Contributor(s):: Supriyo Datta
Everyone is familiar with the amazing performance of a modern laptop, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. What is not as appreciated is the deeper understanding of current flow, energy exchange and device operation that...
Lessons from Nanoelectronics (Q&A)
Q&A session from Lessons from Nanoelectronics.
Solar Cells Lecture 1: Introduction to Photovoltaics
19 Aug 2011 | | Contributor(s):: Mark Lundstrom
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 short-circuit and open-circuit conditions.
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.
