ARO report on materials with spin-mediated thermal properties and call for additional research toward thermoelectrics

By / June 8, 2012

Credit: Nature. Contributed by Pani Varanasi, Program Manager, Physical Properties of Materials, Materials Science Division, Army Research Office: Thermal transport in materials by phonons and electrons is relatively well understood as compared to heat transport in materials by spin excitations (i.e., thermal conductivity in materials due to magnons). Although high thermal conductivity due to magnons has been observed…

Silicon nanomesh demonstrated as thermal conductivity barrier for improving thermoelectrics

By / October 5, 2010

Top: A scanning electron microscope image shows the grid of tiny holes in the nanomesh material. Bottom: In this drawing, each sphere represents a silicon atom in the nanomesh. The colorful bands show the temperature differences on the material, with red being hotter and blue being cooler. Credit: Heath group/Caltech. Thermoelectric materials have great promise…
