Autor: Hofmann, Felix, Garg, Jivtesh, Maznev, Alexei A, Jandl, Adam, Bulsara, Mayank T, Fitzgerald, Eugene A, Chen, Gang, Nelson, Keith A

We have measured the lifetimes of two zone-center longitudinal acoustic phonon modes, at 320 GHz and 640 GHz respectively, in a 14 nm GaAs / 2 nm AlAs superlattice structure. By comparing measurements at 296 K and 79 K we separate the intrinsic contr

Lifetime of sub-THz coherent acoustic phonons in a GaAs-AlAs superlattice

Autor: Maznev, A. A., Hofmann, Felix, Jandl, Adam, Esfarjani, Keivan, Bulsara, Mayank T., Fitzgerald, Eugene A., Chen, Gang, Nelson, Keith A.

Publikováno v: Appl. Phys. Lett. 102, 041901 (2013)

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 conducted at room temperature and liquid nitrogen temperature we separ

Report

Phase-controlled, heterodyne laser-induced transient grating measurements of thermal transport properties in opaque material

Autor: Johnson, Jeremy A., Maznev, Alexei A., Nelson, Keith A., Bulsara, Mayank T., Fitzgerald, Eugene A., Harman, T. C., Calawa, S., Vineis, C. J., Turner, G.

Publikováno v: J. Appl. Phys. 111, 023503 (2012)

The methodology for a heterodyned laser-induced transient thermal grating technique for non-contact, non-destructive measurements of thermal transport in opaque material is presented. Phase-controlled heterodyne detection allows us to isolate pure ph
