  • Raman scattering study of Zn/sup +//P/sup +/ co-implanted GaAs single crystals 
    URSAKI, V. V.; ICHIZLI, V. M.; TIGINYANU, I. M.; TERLETSKII, A. I.; CALUJA, Y. I.; RADAUTSAN, S. I. (IEEE, 1995)
    The activation efficiency of zinc impurity co-implanted with P/sup +/ ions in GaAs single crystals was studied by Raman scattering (RS) at phonon-plasmon coupled modes. P/sup +/ co-implantation has been found to result in ...
  • Resonance Raman scattering and excitonic spectra in TlInS2 crystals 
    ZALAMAI, V. V.; STAMOV, I. G.; SYRBU, N. N.; URSAKI, V. V.; DOROGAN, V. (ELSEVIER, 2015)
    The excitons ground and excited states for Ea and Eb polarizations in absorption and reflection spectra of TlInS2 crystals were detected. The fundamental parameters of excitons and bands were determined at k=0. The ...
  • Resonance Raman scattering by excitonic polaritons in CuGaS2 
    SYRBU, N. N.; BLAZHE, M.; TIGINYANU, I. M.; TEZLEVAN, V. E. (Springer Nature Switzerland, 2002)
    Resonance Raman scattering by exciton polaritons in crystals of CuGaS2 under excitation with the 4880 and 4765 Å lines of an Ar+ laser at 9 K is studied. Lines of one-and two-phonon scattering of excitonic polaritons are ...
  • Resonance Raman scattering in CuGaxAl1-xS2crystals 
    SYRBU, N. N.; TIGINYANU, I. M.; URSAKI, V. V.; DOROGAN, A. V. (IOP Publishing, 2008)
    The change of polarization of the resonant Raman scattering lines is studied in CuGaxAl1−xS2 crystals with x equal to 1, 0.95 and 0.9 assuming resonance conditions with 4880 and 4765 Å Ar laser lines. Linear and circular ...
  • The superposition of one- and two-phonon absorption and radiation in TeO2 crystal 
    SYRBU, N. N.; CREŢU, R. V. (Elservier, 1996)
    Raman scattering and IR reflectivity for actual configuration have been investigated. The contours of reflectivity spectra rave been calculated. Phonon parameters have been determined. The temperature dependence of Raman ...
  • Vibrational modes in ZnAl2S4 and CdIn2S4 crystals 
    SYRBU, N. N.; BOGDANASH, M.; MOLDOVYAN, N. A. (Elservier, 1996)
    Infrared reflectivity spectra and Raman scattering of the ZnAl2S4 and CdIn2S4 crystals have been investigated. Reflectivity spectra contours were calculated and phonon parameters and dielectric constants were determined. ...
  • Vibrational modes of CuAl/sub 1-x/Ga/sub x/Se/sub 2/ solid solution 
    SYRBU, N. N.; BOGDANASH, M.; TEZLEVAN, V. E. (IEEE, 1996)
    In the present paper new results of Raman scattering of CuAl/sub 1-x/Ga/sub x/Se/sub 2/ crystals by the unpolarized light at 77 K are presented. IR reflectivity spectra of this solid solution have been investigated for ...
  • Vibrational study of HgGa2S4 under high pressure 
    VILAPLANA, R.; ROBLEDILLO, M.; GOMIS, O.; SANS, J. A.; MANJÓN, F. J.; PÉREZ-GONZÁLEZ, E.; RODRÍGUEZ-HERNÁNDEZ, P.; MUÑOZ, A.; TIGINYANU, I. M.; URSAKI, V. V. (American Institute of Physics, 2013)
    In this work, we report on high-pressure Raman scattering measurements in mercury digallium sulfide (HgGa2S4) with defect chalcopyrite structure that have been complemented with lattice dynamics ab initio calculations. Our ...
