中文摘要 | a raman-forbidden phonon mode at about 840 cm(-1) is observed popularly on the surface of pun and la-doped bi2sr2-xlaxcuo6+y (0 less than or equal to x less than or equal to 0.8) single crystals annealed in oxygen. a remarkable excitation dependence of this additional line is found. based on the properties of the structure of the bi-o layer with excess oxygen atoms and the similarity in the appearance of the raman-forbidden modes between rba2cu3ox (r = y, nd, gd, pr) and bi2sr2-xlaxcuo6+y systems, we attribute the manifestation of this additional line to the ordering of the interstitial oxygen in the bi-o layers. our results provide raman evidences for confirming that the ordering of the movable oxygen may exist universally in high-temperature superconductors. |
