The essential role of surface pinning in the dynamics of charge density waves submitted to external dc fields

E. Bellec, V. L. R. Jacques, J. Caillaux +1

A Charge Density Wave (CDW) submitted to an electric field displays a strong shear deformation because of pinning at the lateral surfaces of the sample. This CDW transverse pinning…

Evidence of Charge Density Wave transverse pinning by x-ray micro-diffraction

E. Bellec, I. Gonzalez-Vallejo, V. L. R. Jacques +5

Incommensurate charge density waves (CDW) have the extraordinary ability to display non-Ohmic behavior when submitted to an external field. The mechanism leading to this non trivia…
