| dc.description | We have used complex conductivity measurements between 20 Hz and 1 MHz to probe the dielectric response in the low-temperature phase of the (2,5(OCH<sub>3</sub>)<sub>2</sub>DCNQI)<sub>2</sub>Li organic conductor. The observed data reveal the existence of the relaxation process which is well described by a Debye-like expression for an overdamped response of a system with a single degree of freedom. Both the static dielectric constant (ε<sub>0</sub> = 3 × 10<sup>7</sup>) and the characteristic relaxation time (τ<sub>0</sub>) are much larger than that expected for single-particle excitations. τ<sub>0</sub> is thermally activated in a manner similar to the dc conductivity. We attribute the observed relaxation to N = 4 charge density wave pinned by commensurability to the underlying lattice. |
