Electron energy loss spectra of Na0.33CoO2.yH2O (y = 0, 0.6 and 1.3)
J. Q. Li, H. X. Yang, R. J. Xiao +2
Electron energy loss (EEL) spectra have been obtained on materials with the nominal compositions of Na0.33CoO2_yH2O (y = 0, 0.6 and 1.3). Spectral analyses revealed systematic chan…
Structural Phase Transitions and Sodium Ordering in Na0.5CoO2: a Combined Electron Diffraction and Raman Spectroscopy Study
H. X. Yang, C. J. Nie, Y. G. Shi +6
The nonstoichiometric NaxCoO2 system exhibits extraordinary physical properties that correlate with temperature and Na concentration in its layered lattice without evident long-ran…
Phase separation, effects of magnetic field and high pressure on charge ordering in y-Na0.5CoO2
H. X. Yang, Y. G. Shi, C. J. Nie +7
Transmission electron microscopy observations reveal the presence of complex superstructures and remarkable phase separation in association with Na-ordering phenomenon in y-Na0.5Co…
Superstructure, sodium ordering and antiferromagnetism in NaxCoO2 (0.75<x<1.0)
Y. G. Shi, H. C. Yu, C. J. Nie +1
Transmission-electron-microscopy investigation reveals the presence of a superstructure with a doubled period of 2d110 in the NaxCoO2 materials for x ranging from 0.75 to 1.0. Syst…
