Impurity modes and effect of clustering in diluted semiconductor alloys
Andrei Postnikov, Olivier Pages, Ayoub Nassour +1
The variation of TO zone-center vibration spectra with concentration in mixed zincblende-type semiconductors can be understood within a paradigm of unified "one bond - two modes" a…
Linearized force constants method for lattice dynamics in mixed semiconductors
Ayoub Nassour, Joseph Hugel, A. V. Postnikov
A simple and accurate method of calculating phonon spectra in mixed semiconductors alloys, on the basis of preliminarily (from first principles) relaxed atomic structure, is propos…
Isolated modes and percolation in lattice dynamics of (Be,Zn)Se
A. V. Postnikov, O. Pages, T. Tite +2
A mixed II-VI semiconductor Zn[1-x]Be[x]Se possesses non-trivial vibration properties, because its two constituent compounds, ZnSe and BeSe, show very different degree of covalency…
Implementation of the Projector Augmented Wave LDA+U Method: Application to the Electronic Structure of NiO
O. Bengone, M. Alouani, P. Bloechl +1
The so-called local density approximation plus the multi-orbital mean-field Hubbard model (LDA+U) has been implemented within the all-electron projector augmented-wave method (PAW)…
