Abstract

Dependence of static dielectric susceptibility and correlation length of charge density waves (CDW) with weak defects on parameter of incommensurability with lattice is investigated. In almost commensurate phase (h-hc hc), χ ∼ (h-hc) 1 3 In -4 3 hc/h-hc and Rc ∼ (h - hc) 2 3. In 1 3 hc/h - hc. Far from commensurability (h≫hc) χ∼ (a+h2c/h2) -2 3, Rc ∼ (a + h2c/h2) -2 3, where a is the dimensionless ratio of random potential intensities, corresponding to backward and forward scattering impurities.
