- 論文の詳細を見る
Temperature dependence of Raman spectra in 4Hb-Talc. was studied. The high-frequency spectra of 4f#-TaSe. consist of 17'-TaSe.- and 2#-TaSe.-like modes. Inrelation to the two charge-density-wave phase transitions occurring in the octahedral(OH) and the trigonal-prismatic (TP) layers, two kinds of soft modes were observed.Mode repulsion was observed in the A. and E.. soft modes which are related to thephase transition of the OH layer. The two-phonon overtone scattering of the Kohn-anomaly modes of the TP layer was observed. The frequency of the lower edge of thismode corresponds to twice the minimum frequency of the Kohn-anomaly mode.From this frequency, temperature dependence of the electronic susceptibility of theTP layer was estimated. An E.. rigid-layer mode was observed at 16.5 cm '.
