Phonon softening and "forbidden" mode observed by Raman scattering in Na0.5CoO2
Q. M. Zhang, M. an, S. K. Yuan +6
Polarized Raman scattering measurements have been performed on Na0.5CoO2 single crystal from 8 to 305 K. Both the A1g and E1g phonon modes show a softening below Tc1 ~ 83 K. Additi…

Infrared spectroscopy of the charge ordering transition in NaCoO
N. L. Wang, Dong Wu, G. Li +3
We report infrared spectra of a NaCoO single crystal which exhibits a sharp metal-insulator transition near 50 K due to the formation of charge ordering. In comparison…
