Abstract :
We measured thermoelectric power and Raman spectra for (Me2DCNQI)2CuxLi1−x. The ν8 (quinoid CN stretch) Raman line shifts downwards with an increase of copper contents (x), and exhibits a split for x≤0.24. Temperature dependence of the thermoelectric power exhibits drastic change between x=0.14 and x=0.22. This behaviour is consistent with the phase diagram previously determined.
