Low Temperature Enhancement of the Thermoelectric Seebeck Coefficient in Semiconductor Nanoribbons
21 Oct 2016 | | Contributor(s):: Kommini Adithya, Zlatan Aksamija
IWCE 2015 Presentation. We propose a novel approach to achieving a narrow window-shaped TDF through a combination of a step-like 2-dimensional density-of-states (DOS) and inelastic optical phonon scattering. A shift in the onset of scattering with respect to the step-like DOS creates a TDF which...
Ultra-Thin Silicon Membranes and Nanowires as Nanophononic and Thermoelectric Devices
10 Feb 2016 | | Contributor(s):: Davide Donadio
IWCE 2015 presentation. Engineering silicon at the nanoscale paves the way to new applications of this cheap, abundant, and technologically and environmentally friendly material. Transistors in nanoelectronics have reached the 10 nm size limit, implying very high density but also critical issues...

This tool simulates a practical thermoelectric cooler unit with atomistic models
Physics and Simulation of Nanoscale Electronic and Thermoelectric Devices
25 Jun 2013 | | Contributor(s):: raseong kim
For the past few decades, transistors have been continuously scaled. Dimensions are now at the nanoscale, and device performance has dramatically improved. Nanotechnology is also achieving breakthroughs in thermoelectrics, which have suffered from low efficiencies for decades. As the device...
Landauer Approach to Thermoelectrics
21 Jun 2013 | | Contributor(s):: Changwook Jeong
Many efforts have been made to search for materials that maximize the thermoelectric (TE) figure of merit, ZT, but for decades, the improvement has been limited because of the interdependent material parameters that determine ZT. Recently, several breakthroughs have been reported by applying...
[Illinois] Nano EP Series: Thermoelectrics of Roughened Silicon Nanowire Arrays
12 Dec 2012 | | Contributor(s):: Jyothi Sadhu
"Thermoelectrics of Roughened Silicon Nanowire Arrays"The possibility of using silicon as a thermoelectric material for waste heat recovery is technologically significant due to silicon's economy of scale and vast processing knowhow. Patterning silicon as nanowires with roughened sidewalls is...

"Thin-Film Nanocalorimetry of Lamellar Silver Alkanethiolate Crystals"Materials exhibit unique thermodynamic properties at the nanoscale.The study of size-dependent phenomena is critical in our understanding of nanoscale systems.We have developed an ultra-sensitive, fast-scanning thin film...
Nano Solutions to Our Impending Energy Crisis
11 Nov 2012 | | Contributor(s):: Ali Shakouri
In this talk we review some of the advances in nanoscale energy conversion devices and discuss about the challenges and opportunities to provide a clean energy infrastructure. Couple of examples from solar and thermoelectric materials, devices and systems will be given and the scale of the...
Dynmical Models for Thermopower
19 Apr 2012 | | Contributor(s):: Giulio Casati
Dynamical nonlinear systems provide a new approach to the old problem of increasing the efficiency of thermoelectric machines. Here we discuss stylized models of classical dynamics, including non interacting complex molecules in an ergodic billiard, a disordered hardpoint gas and systems with...
