摘要：

We report on the temperature dependence of the electrodynamic response of the CDW model compound K0.3Mo03 and its alloys. We found clear evidence of a pseudogap excitation and of the formation of a narrow Drude-like resonance at T>T(CDW), as consequence of the precursor effects of the CDW phase transition. Moreover, we found signatures of the important role played by the thermal lattice fluctuations on the electrodynamic properties.
