ECE 656 Lecture 41: Transport in a Nutshell
21 Feb 2012 | | Contributor(s):: Mark Lundstrom
Energy Dissipation at the Nanoscale: from graphene to phase-change materials
20 Dec 2011 | | Contributor(s):: Eric Pop
This talk will present recent highlights from our studies of dissipation in novel nanoelectronics based on graphene and phase-change materials. We have investigated both Joule heating and Peltier cooling in graphene electronics, and found that the latter could be tuned to partially remove the...
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.
On-Chip Thermoelectric Cooling Tool
29 Mar 2011 | | Contributor(s):: Shuaib Salamat, David Alberto Saenz
Simulates an embedded spot peltier cooler on a chip 1D thermal profile.
27 Jul 2011 | | Contributor(s):: Dragica Vasileska
This set of lecture notes explains electro-thermal and thermo-electric effects as they occur in semiconductor materials and devices.
Thermoelectric effects in semiconductor nanostructures: Role of electron and lattice properties
29 Sep 2010 | | Contributor(s):: Abhijeet Paul, Gerhard Klimeck
This presentation covers some aspects of present development in the field of thermoelectricity and focuses particularly on the silicon nanowires as potential thermoelectric materials. The electronic and phonon dispersions are calculated and used for the calculation of thermoelectric properties...
25 Jul 2010 | | Contributor(s):: Mark Lundstrom
his talk is an undergraduate level introduction to the field. After a brief discussion of applications, the physics of the Peltier effect is described, and the Figure of Merit (FOM), ZT, which controls the efficiency of a thermoelectric refrigerator or electric power generator, is discussed. The...
