We present a Raman scattering study of wurtzite ZnO over a temperature range from 80 to
750 K. Second-order Raman features are interpreted in the light of recent ab initio phonon …

The resonance of the Raman scattering by E 2, A 1 T, E 1 L, and E 1 T phonons, and several
second-order features, has been studied for ZnO for photon energies between 1.6 and 3 eV …

We have performed first-principles calculations of the electronic structure of ZnO, and
applied them to the determination of structural and lattice-dynamical properties and their …

Phonon linewidths can exhibit a large variation when either pressure or isotopic masses are
changed. These effects yield detailed information about the mechanisms responsible for …

The dispersion of the Raman cross sections of several phonon modes in CdS and ZnO
using a wide range of laser energies has been measured. The E 1 (LO) and multi-LO (2-LO …

The high-pressure behavior of optical phonons in wurtzite zinc oxide (w− ZnO) is studied
using room-temperature Raman spectroscopy and ab initio calculations based on a plane …

Using Raman backscattering spectroscopy we have observed six local vibrational modes in
as-grown state-of-the-art nominally undoped zinc oxide single crystals. The local vibrational …

Zinc oxide is a key material for optoelectronic applications, whose transport properties are
typically dominated by the lattice vibrations. We report here the phonon-dispersion relations …

The exponential absorption edge (known as Urbach's rule) observed in most materials is
interpreted in terms of thermal fluctuations in the band-gap energy. The main contribution to …

Multiphonon scattering has been observed in ZnO by means of uv laser Raman studies.
Phonon-scattering shifts greater than 4000 cm− 1 are observed. Comparisons are made …
