Abstract
We suggest a theoretical picture for distributions of plastic deformations experienced by
a sliding Charge Density Wave in the course of the conversion from the normal current at the contact
to the collective one in the bulk. Several mechanisms of phase slips via creation and proliferation of
dislocations are compared. The results are applied to space resolved X-ray [1,2], multi-contact [3,4]
and optical [5] studies. Numerical simulations are combined with model independent relations.
