| 中文摘要 | Structural and physical properties of NaxCoO2 and superconducting Na(x)CoO(2)center dot yH(2)O hydrates have been systematically investigated. Raman scattering measurements reveal that the five active phonons in NaxCoO2-yH(2)O System change systematically with the H2O intercalation and modification of superconductivity, in particular the A(1g) and E-1g modes in correlation with oxygen movements. Incoherent inelastic neutron scattering (IINS) study on the local structure of H2O-layers in NaxCoO2-yH(2)O (0 <= y <= 1.8) suggests the presence of three types of clusters, H3O+, H5O+ and ice-1h like weakly bonded water, among CoO2 sheets. Electron energy loss (EEL) analysis on Na0.33CoO2 center dot yH(2)O (0 <= y <= 1.3) indicates certain notable changes in the electronic structure during hydration. Microstructure and structural phase transitions accompanied with local atomic ordering in the charge-ordered phase Na0.5CoO2 have been investigated along with the hexagonal-orthorhombic phase transition.
