Intrinsic to extrinsic phonon lifetime transition in a GaAs–AlAs superlattice

Intrinsic to extrinsic phonon lifetime transition in a GaAs–AlAs superlattice

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