Raman Spectra of [N(CH3)4]2ZnCl4 Single Crystals. II. Raman Spectra of Low-Symmetry Phases

Autor: Yu. I. Yuzyuk, Victor I. Torgashev, Yu. I. Durnev, L. M. Rabkin

Publikováno v: physica status solidi (b). 167:321-335

Polarized Raman spectra of [N(CH3)4]2ZnCl4 single crystals are studied in five low-symmetry phases in the frequency range 10 cm−1 < ν < 3500 cm−1. The observed lines are assigned on the basis of a factor-group analysis and corresponding correlat

Vibrational Spectra and Phase Transitions in Layered Semiconducting Ferroelectrics with TlGaSe2 Structure. I. Temperature Dependences of Parameters of the Raman Spectrum Lines of TlGaSe2

Autor: Yu. I. Yuzyk, B. S. Kulbuzhev, Victor I. Torgashev, Yu. I. Durnev, A. U. Malsagov, L. M. Rabkin

Publikováno v: physica status solidi (b). 153:517-527

Raman spectra of TlGaSe2 single crystals are obtained in the temperature range 85< T < 300 K, which includes the phase transition points. Fitting of the spectra, using the model of additive damped oscillators and a relaxator, yields quantitative info
