| Abstract: | The low-frequency dielectric susceptibility of layered CuInP2(SexS1-x)6 mixed crystals is investigated. The morphotropic phase boundary is found between x = 0.75 and 0.8. Broadening of phase transition anomalies in CuIn@S6 is observed at substitution of sulfur atoms by selenium. At substitution of selenium by sulfur in CuInP2Se6 a second order phase transition from the paraelectric phase to an intermediate phase is clearly observed up to the morphotropic boundary, while dielectric anomalies at the first order transition from the intermediate phase to ferrielectric phase are completely extinguished. |
