Phonon dispersion in ZnO has been mapped for frequencies up to 4× 10 12 c/sec. A
postulated low frequency mode does not exist, and the results are in good agreement with …

We investigate the origin of the band at 3.31 eV (A band) commonly observed in the
emission spectra of various ZnO samples. This band is of prime importance for the …

Soft x-ray emission and absorption spectroscopy of the O K-edge are employed to
investigate the electronic structure of wurtzite ZnO (0001). A quasiparticle band structure …

Raman backscattering measurements were performed on single crystal ZnO for different
excitation wavelengths before and after ion implantation with hydrogen and nitrogen. In …

We report the analysis of the Urbach effect in the absorption spectra of the undoped ZnO thin
films. The absorption coefficients of the ZnO thin films show the exponential rise, also known …

Raman scattering at room temperature is reported in Zn 1− x Mn x O nanoparticles for the
range of 0⩽ x⩽ 0.15⁠. The effect of compositional disorder is obtained by analyzing the …

We examine how the short-range part of the electron–hole exchange interaction influences
the strain-induced variations of the oscillator strength in ZnO films. Our model enables us to …

The emission and reflection spectra of ZnO have been investigated in the intrinsic region
and the data have been interpreted in terms of the wurtzite crystal band structure. Free …

Two hydrogen-related defects in ZnO are identified by a combination of local vibrational
mode spectroscopy and first-principles theory. The HI center consists of one hydrogen atom …

A combined study of Raman scattering, IR absorption, photoluminescence, and
photoconductivity was performed in ZnO. Two shallow donors—hydrogen at the bond …
