Long-lived optical phonons in ZnO studied with impulsive stimulated Raman scattering

C. Aku-Leh, J. Zhao, R. Merlin +2

The anharmonic properties of the low-frequency E2 phonon in ZnO were measured using impulsive stimulated Raman scattering. At 5 K, the frequency and lifetime are (2.9787 +/- 0.0002…
