Raman scattering study of phonon and spin modes in (TMTSF)2PF6
Z. V. Popovic, V. A. Ivanov, O. P. Khoung +3
We have studied polarized Raman spectra of (TMTSF)2PF6 single crystals in the wide spectral and temperature range using different laser energies. We observed and assigned 23 Raman…
Optical studies of gap, hopping energies and the Anderson-Hubbard parameter in the zigzag-chain compound SrCuO2
Z. V. Popovic, V. A. Ivanov, M. J. Konstantinovic +8
We have investigated the electronic structure of the zigzag ladder (chain) compound SrCuO2 combining polarized optical absorption, reflection, photoreflectance and pseudo-dielectri…
Optical Properties of the Spin-Ladder Compound Sr_{14}Cu_{24}O_{41}
Z. V. Popović, M. J. Konstantinović, V. A. Ivanov +4
We report the measurements of the pseudodielectric function, far-infrared reflectivity and Raman scattering spectra in Sr_{14}Cu_{24}O_{41} single crystal. We study the lattice and…
Effective Dimensionality and Band Structure of alpha-Nav_2o_5 Compound: 1D or 2D?
V. A. Ivanov, Z. V. Popovic, P. Khuong +1
The AV_nO_{2n+1} mixed valence compounds (n=1, A=Na) are classified as dimerized layered system with strongly interacting d-electrons of vanadium ions. The derived band gaps, energ…
