Intrinsic to extrinsic phonon lifetime transition in a GaAs-AlAs superlattice
Felix Hofmann, Jivtesh Garg, Alexei A Maznev +5
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 co…

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…
