Mechanism of Liquid Crystalline Semiconductor Driven by Nuclear Tunneling with Correlated Gaussian Disorder

Abstract

We have been investigating the charge transport in organic semiconductors exhibiting smectic E phase. Wepropose a new charge transport model applying the quantum CT rate proposed by Lin et a1 [4] with nuclear tunnelingeffects on the Gaussian energy landscape, which is used in Gaussian Disorder Model (GDM). The model can explainthe characteristic field and temperature dependence of mobility in the liquid crystals. We demonstrate how the staticdisorder disturbs poralonic transport and propose the concept how we can characterize the electron transport driven byNuclear tunneling with Correlated Gaussian Disorder.
