Oxygen vacancies in ZnO

A Janotti, CG Van de Walle - Applied Physics Letters, 2005 - pubs.aip.org
The electronic properties of ZnO have traditionally been explained by invoking intrinsic
defects. In particular, the frequently observed unintentional n-type conductivity has often …

Raman spectrum of cubic ZnS

WG Nilsen - Physical Review, 1969 - APS
We present a detailed study of the first-and second-order Raman effect in cubic ZnS using
both 4880 and 5145 Å excitation. Our primary interest is to determine to what extent …

various excitons and their phonon replicas in high-purity bulk ZnO has been studied at …

Pressure-induced softening of shear modes in wurtzite ZnO: A theoretical study

A Zaoui, W Sekkal - Physical Review B, 2002 - APS
Recent ultrasonic experiments on single-crystal specimens of the wurtzite (B 4) phase of
ZnO have shown that, under pressure, this material becomes softer against shear-type …

Multi-wavelength Raman scattering of nanostructured Al-doped zinc oxide

Ultrafast screening and carrier dynamics in ZnO: Theory and experiment

MAM Versteegh, T Kuis, HTC Stoof, JI Dijkhuis - Physical Review B, 2011 - APS
At carrier densities above the Mott density, Coulomb screening destroys the exciton
resonance. This, together with band-gap renormalization and band filling, severely affects …

Effects of Hubbard term correction on the structural parameters and electronic properties of wurtzite ZnO

ES Goh, JW Mah, TL Yoon - Computational Materials Science, 2017 - Elsevier
The effects of including the Hubbard on-site Coulombic correction to the structural
parameters and valence energy states of wurtzite ZnO were explored. Due to the changes in …

Size dependence of electron-phonon coupling in ZnO nanowires

RP Wang, G Xu, P Jin - Physical Review B, 2004 - APS
Raman spectra of ZnO powder and free-standing nanowires prepared by laser ablation
have been studied. All observed vibrational modes in ZnO powder, both first order and …

Raman study of N+-implanted ZnO

JB Wang, HM Zhong, ZF Li, W Lu - Applied physics letters, 2006 - pubs.aip.org
Raman scattering has been used to study the influence of nitrogen, a potential acceptor in
