Thermal transport in suspended silicon membranes measured by laser-induced transient gratings
Alejandro Vega-Flick, Ryan A. Duncan, Jeffrey K. Eliason +12
Studying thermal transport at the nanoscale poses formidable experimental challenges due both to the physics of the measurement process and to the issues of accuracy and reproducib…
Ultrafast structural dynamics of the Fe-pnictide parent compound BaFe2As2
L. Rettig, S. O. Mariager, A. Ferrer +8
Using femtosecond time-resolved x-ray diffraction we investigate the structural dynamics of the coherently excited A1g phonon mode in the Fe-pnictide parent compound BaFe2As2. The…
Reconstructing phonon mean free path contributions to thermal conductivity using nanoscale membranes
John Cuffe, Jeffery K. Eliason, Alexei A. Maznev +8
Knowledge of the mean free path distribution of heat-carrying phonons is key to understanding phonon-mediated thermal transport. We demonstrate that thermal conductivity measuremen…
Structural and Magnetic Dynamics in the Magnetic Shape Memory Alloy NiMnGa
S. O. Mariager, C. Dornes, J. A. Johnson +11
Magnetic shape memory Heusler alloys are multiferroics stabilized by the correlations between electronic, magnetic and structural order. To study these correlations we use time res…
Direct Measurement of Room Temperature Non-diffusive Thermal Transport Over Micron Distances in a Silicon Membrane
Jeremy A. Johnson, A. A. Maznev, John Cuffe +6
The "textbook" phonon mean free path (MFP) of heat carrying phonons in silicon at room temperature is ~40 nm. However, a large contribution to the thermal conductivity comes from l…
