By method of dielectric spectroscopy we have obtained experimental data concerning the 4k F charge density wave (CDW) associated with the charge ordering (CO) state of Wigner type in (TMTTF) 2 X conductors. A divergence of the relaxation time was fou

We present experimental evidence and a corresponding theory for the ferroelectric transition in the family of quasi-one-dimensional conductors $(\mathrm{TMTTF}{)}_{2}X$. We interpret this new transition in the frame of the combined Mott-Hubbard state

We have determined the spatial distribution of the local charge-density-wave (CDW) strain in the sliding state of NbSe 3 . The strain is measured by monitoring the spatially-varying shift q(x) of the CDW satellite wave vector between current contacts

We present results on the normal-collective current conversion processes and associated deformation profile for a charge density wave in the sliding state. High resolution x-ray measurements of the satellite positional shift have been performed on ${

The permittivity of monoclinic TaS3, a quasi-one-dimensional conductor with an incommensurate charge density wave (CDW), as a function of frequency and temperature has been studied. At low temperatures and at frequencies below 1 MHz, the temperature

A well-formed energy gap Δ is observed in the energy spectrum of the quasi-one-dimensional orthorhombic conductor TaS3 at temperatures much lower than the Peierls transition temperature TP. As the temperature increases, in the region T>TP/2 there is

We show that the newly discovered phase transitions in (TMTTF)2X (X=PF6, AsF6, SbF6, ReO4) are characterised by a huge divergent peak in the low frequency dielectric constant. These phase transitions can be explained by combined effect of charge disp

The spatial distribution of the electric field E between two current terminals along the quasi-one-dimensional TaS3 conductor has been studied using a multicontact configuration. In the low-temperature range (30 VT the spatial distribution of E is go
