Sažetak
Polarized reflection measurements have been performed on the charge-density-wave compound K0.3MoO3 from room temperature down to T=50 K. For the first time, the least conducting direction (perpendicular to the planes of MoO6-octahedrons) was investigated in the entire infrared range of frequency. The diatomic MoO stretching vibrations centered around 940 cm−1 exhibit an unusual temperature dependence ; below some characteristic temperature the line shape changes significantly. The observed features are attributed to change-density-wave fluctuations that are present well above the charge-density-wave transition TCDW, and start to develop short-range order at T⁎
