Charge ordering phase transition and order - disorder effects in the Raman spectra of NaV
In the ac polarized Raman spectra of NaV 2 O 5 we found anomalous phonon broadening and the energy shift as a function of the temperature, which we relate to the translational symmetry breaking effects caused by the strong electrical disorder due to the fluctuating nature of V 4.5+ valence state of vanadium. The structural correlation length, obtained from comparison between measured and calcul...
متن کاملRaman Spectra and Structural Analysis in ZrOxNy Thin Films
Raman spectroscopy has been used as a local probe to characterize the structural evolution of magnetron-sputtered decorative zirconium oxynitride ZrOxNy films which result from an increase of reactive gas flow in the deposition The lines shapes, the frequency position and widths of the Raman bands show a systematic change as a function of the reactive gas flow (a mixture of both oxygen and nitr...
متن کاملRaman signatures of inversion symmetry breaking and structural phase transition in type-II Weyl semimetal MoTe2
Transition metal dichalcogenide MoTe2 is an important candidate for realizing the newly predicted type-II Weyl fermions, for which the breaking of the inversion symmetry is a prerequisite. Here we present direct spectroscopic evidence for the inversion symmetry breaking in the low-temperature phase of MoTe2 by systematic Raman experiments and first-principles calculations. We identify five latt...
متن کاملStructural Chemistry and Raman Spectra of Niobium Oxides
The pyrolysis of TVSb has been investigated in a flow tube reactor using Dz and He carrier gases. For TVSb alone, the most likely pyrolysis reaction involves an Sbcentered reductive elimination pathway. A less likely possibility is pyrolysis via homolysis of the Sb-C bonds, yielding vinyl radicals. Unfortunately, examination of the organic byproducts in both He and D, yields insufficient inform...
متن کاملJa n 20 01 Charge - ordering phase transition and order - disorder effects in the Raman spectra of NaV
In the ac polarized Raman spectra of NaV 2 O 5 we have found anomalous phonon broadening, and an energy shift of the low-frequency mode as a function of the temperature. These effects are related to the breaking of translational symmetry, caused by electrical disorder that originates from the fluctuating nature of the V 4.5+ valence state of vanadium. The structural correlation length, obtained...
