Symposium on Nanomaterials for Energy: Nanostructured Thermoelectric Materials for Waste Heat Recovery
11 May 2015 | Online Presentations | Contributor(s): Ali Shakouri
Energy consumption in our society is increasing rapidly. A significant fraction of the energy is lost in the form of heat. In this talk we introduce thermoelectric devices that allow direct conversion of heat into electricity. Novel metal-semiconductor nanocomposites are developed where the heat and charge transport are modified at the atomic level. Theory and experiment are compared for embedded ErAs nanoparticles in InGaAlAs semiconductor matrix as well as for ScN/ZrHfN metal semiconductor multilayers. Potential to increase the energy conversion efficiency and bring the cost down to $0.1-0.2/W will be discussed.

nanoHUB-U TEAS Thermoelectricity - Atoms to Systems: Scientific Overview
10 Oct 2013 | Online Presentations | Contributor(s): Ali Shakouri, Supriyo Datta, Mark Lundstrom
This five-week short course aims to introduce students to the thermoelectric theory and applications using a unique, “bottom up” approach to carrier transport that has emerged from research on molecular and nanoscale electronics. Intuition about thermoelectric relations and efficiency limits are obtained by studying a single atom. The first two weeks of the course introduce this new perspective and connects it to the traditional treatment of thermoelectric science. Landauer formalism provides a unified framework to study both electron and phonon transport.

Nanoscale Opto Thermo Electric Energy Conversion Devices
28 May 2008 | Online Presentations | Contributor(s): Ali Shakouri
We review solid-state devices that allow direct conversion of heat into electricity. We describe fundamental and practical limits of conventional thermoelectric materials. Novel metal-semiconductor nanocomposites are developed where the heat and charge transport are modified at the atomic level. Potential to reach high power densities and high conversion efficiencies will be discussed. We also describe how similar principles can be used to reduce heating in optoelectronic devices and make micro refrigerators on a chip in order to remove hot spots in integrated circuits.
