Abstract
We develop here a microscopical model of quasi-regular impurity distribution driven by the CDW appropriate for highly mobile impurities or materials with fictitious CDW transition temperature. Thermal hysteresis effects at the CDW transition reported in the quasi-1D materials NbSe3 and Ta2NiSe7, could be interpreted in the framework of the present model. Possible connections with other (alloy, heavy-fermion) systems are also suggested.
