Thermoelectric power and Raman spectra of (Me2DCNQI)2CuxLi1−x

Abstract We measured thermoelectric power and Raman spectra for (Me 2 DCNQI) 2 Cu x Li 1− x . The ν 8 (quinoid CN 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.
