Long-Lived Coherent Acoustic Phonons in Epitaxially Grown III-V Adiabatic Cavities

Muhammad Hanif, Milos Dubajic, Sandeep. J. Sreerag +4

We provide evidence of strongly confined coherent acoustic phonons inside high quality factor phononic cavities that exhibit tailoredphonon potentials. Using GaAs/AlAs quasiperiodi…
