Nanoscale thermal
transport
In this
project we study the flow of phonons in nanoscale structures and
materials. Thus we are able to obtain predictive calculations of
thermal conductivity and other properties. We have developed new
theoretical techniques, and successfully applied them to study nanowire
thermal transport. Good agreement with experimental results has been
obtained in those cases in which experiments are available.

Nanoscale thermoelectricity
This project is aimed at accurately computing the thermoelectric properties of nanoscale structures and materials. By iterative solution of the Boltzmann transport equation, quantitative limitations to the figure of merit enhancement in nanowires are found.
