Effect of impurities on the dielectric response of the charge-density wave in K0.3MoO3

摘要: We present the results of experiments in which characteristics low-frequency relaxation charge-density wave (CDW) ${\mathrm{K}}_{0.3}$${\mathrm{MoO}}_{3}$ ``blue bronze'' have been determined presence weakly perturbing (Rb substituted for K) and strongly (W Mo) impurities. Both mean time static dielectric constant decrease The temperature dependence CDW has studied between approximately 25 90 K, displays both similarities differences from we obtained pure blue bronze. discuss within context classical model transport.
