Conduction and optical effects in the plastic charge-density waves

Résumé

The creep motion of the charge-density wave (CDW) and its modulation through optical excitation in the low-temperature state of K0.3MoO3 are analyzed in terms of a local pinning theory, in which local metastable states created by pinning induced phase dislocations are considered. The nonlinear I-V curve below the sliding threshold field (Vs) can be well reproduced with a numerical calculation, and it is shown that photoexcitation increases the transition probability of phase slips, which promotes the creep motion, and also leads to a relaxation of the phase strain.
