Sažetak
We overview complex conductivity measurements (10mHz-1MHz) in low-dimensional organic systems k-(BEDT-TTF)2Cu[N(CN)2]Cl, and deuterated Cu-DCNQI and its alloys, with commensurate density wave ground states. We discuss the obtained results in comparison with those for the incommensurate density waves, like in (TMTSF)2PF6, in which the phason relaxation in a disordered background dominates. We show that in the commensurate systems with a random, temperature dependent, domain structure charged domain walls provide a more appropriate description of the observed dielectric relaxation.
