Lifetime of sub-THz coherent acoustic phonons in a GaAs-AlAs superlattice
A. A. Maznev, Felix Hofmann, Adam Jandl +5
We measure the lifetime of the zone-center 340 GHz longitudinal phonon mode in a GaAs-AlAs superlattice excited and probed with femtosecond laser pulses. By comparing measurements…
Nonlinear terahertz metamaterials via field-enhanced carrier dynamics in GaAs
Kebin Fan, Harold Y. Hwang, Mengkun Liu +7
We demonstrate nonlinear metamaterial split ring resonators (SRRs) on GaAs at terahertz frequencies. For SRRs on doped GaAs films, incident terahertz radiation with peak fields of…
Femtosecond nonlinear ultrasonics in gold probed with ultrashort surface plasmons
Vasily V. Temnov, Christoph Klieber, Keith A. Nelson +6
Fundamental interactions induced by lattice vibrations on ultrafast time scales become increasingly important for modern nanoscience and technology. Experimental access to the phys…
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…
