Charge-ordering signatures in the optical properties of beta-Na0.33V2O5.

1 3 N ov 2 00 2 Charge and sodium ordering in β − Na 0 . 33 V 2 O 5 Raman and optical spectroscopy

Polarized Raman and optical spectra for the quasi-one dimensional metallic vanadate β−Na0.33V2O5 are reported for various temperatures. The spectra are discussed in the light of the sodium and charge ordering transitions occurring in this material, and demonstrate the presence of strong electron-phonon coupling.

First-Principles Study of Structure, Electronic and Optical Properties of HgSe in Zinc Blende (B3) Phase

In this paper, the structural parameters, energy bands structure, density ofstates and charge density of HgSe in the Zincblende(B3) phase have been investigated.The calculations have been performed using the Pseudopotential method in theframework of density functional theory (DFT) by Quantum Espresso package. Theresults for the electronic density of states (DOS) show tha...

Signatures of polaronic charge ordering in optical and dc conductivity using dynamical mean field theory

تحلیل پراکندگی پرتوهای X تشدید یافته در لبه K ی Mn در Nd./5Sr./5MnO3

 Studies of phenomena such as charge, orbital and spin ordering in manganite has attracted much interest in recent years. These studies have been possible from an experimental point of view by the third generation synchrotron sources. X-ray with high flux density, tunable energy and polarization can be produced in synchrotron sources. Experiments have shown a resonant in peak intensity originat...
