title = "Anharmonic interactions in ZnO probed with impulsive stimulated Raman scattering",
abstract = "Impulsive stimulated Raman scattering studies of ZnO show a dramatic increase in the lifetime of the low-energy E2 optical phonon from 34 ps at 292 K to 211 ps at 5 K. The frequency of this mode at 5 K is (2.9789 ± 0.0002) THz, giving a quality factor Q ∼ 2000. The temperature-dependent lifetime is dominated by two-phonon up-conversion processes and, at low temperatures, the lifetime is limited by isotopic disorder.",
