Engineering thermal transport in SiGe-based nanostructures for thermoelectric applications
Published in Journal of Materials Research, 2015
This article considers phonon transport in a broad range of nanostructured materials made from Si, Ge, and their alloys. We demonstrate that thermal transport in SiGe nanostructures is tuneable by sample size (thin films), period thickness (SLs), and grain size (nanocomposites) through boundary scattering. Our results are relevant to the design of nanostructured SiGe alloys for thermoelectric applications.
Thermal conductivity as a function of Ge composition is shown for bulk and thin films.
