Charge-density-wave fluctuation contribution to the thermal conductivity of K_0.3MoO_3

The thermal conductivity of the charge-density-wave compound K_0.3MoO_3 has been investigated in the chain direction and in both perpendicular directions. A strong anisotropy is observed in the temperature range 100-300 K. The detailed analysis of the temperature dependence in all three directions confirms that in addition to the lattice and free carriers there are very anisotropic contributions to the thermal conductivity coming from the phase and amplitude fluctuations.
