中文摘要 | Raman spectroscopy measurements have been performed on alpha-, beta-, and gamma-NaxCoO2 phases differing in their stacking of CoO6 octahedra along the c-axis direction. The results demonstrate that, in general, there are five Raman active phonons for gamma-Na0.75CoO2, two Raman active phonons for alpha-NaCoO2, and three Raman peaks for beta-Na0.6CoO2. We have also performed Raman-scattering measurements on several gamma-(Ca,Sr)(x)CoO2 (0.15 <= x <= 0.40) samples which show well-defined intercalated Ca/Sr ordering. The experimental data show that the intercalated cation ordering could result in visible alterations on Raman spectral structures. The observations of the spectral changes along with the variation of the CoO6 stacking, as well as the intercalated Sr/Ca ordering suggest that the interlayer interaction plays an important role for understanding the phonon properties in this layered system. |
