On the critical current for the charge density wave transport
Keyword(s):
We report transport measurements under very high current densities j, up to 108 A/cm2, of quasi-one-dimensional charge-density wave (CDW) conductors NbSe3 and TaS3. Above $j_0-10^1$ A/cm2 the point contacts NbSe3-NbSe3 show a sharp singularity, and the TaS3 nanosamples show metallic temperature dependence (positive dR/dn. We interpret both results as an evidence for the suppression of the Peierls gap 2A and development of the metallic state above j0. Possible scenarios of the Peierls state destruction are discussed.
