摘要：

We use a phenomenological model to find theoretically the non-linear dielectric effect (NDE) in the isotropic phase above the isotropic to chiral smectic-C (I-SmC*) phase transition. We find an analytical expression for the NDE in the isotropic phase above the I-SmC* phase transition. The temperature dependence of the NDE is presented in the isotropic phase of the I-SmC* phase transition. (C) 2008 Elsevier B.V. All rights reserved.
