Thermoelectric transport and structural changes in charge-density-wave system (NbSe4)10/3I

In order to get better insight into the electrical and thermal transport of (NbSe4)10/3 we performed a detailed measurements of the electrical conductivity and thermopower from 350 K down to 5 K as well as structural investigation in the vicinity of the Peierls transition on the samples selected from the same batch. The observed structural changes are not enough to explain the anomalous behaviour of the transport properties. It seems that the origin of observed anomalies one should search in the interplay of the distortion of the underlying lattice and the distortion of charge-density-wave lattice
