Tbte3 raman
WebRaman spectroscopy on RTe3 shows that the ΩTe mode cannot be assigned to one of the four Raman-active A1g modes predicted for the undistorted lattice, and that it probably results from the CDW (26). This oscillation is robustly present in all our measurements, regardless on BZ position, temperature, or pump power. However, literature WebWe use high-resolution synchrotron x-ray diffraction to uncover a second, low-temperature, charge density wave (CDW) in TbTe_3. Its T_(c2) = 41.0 +/- 0.4 K is the lowest discovered so far in the rare earth telluride series. The CDW wave vectors of the high temperature and low temperature states differ significantly and evolve in opposite directions with …
