Remnant Polarization in Thin Films from a Columnar Liquid Crystal

摘要

Organic thin films with a large remnant polarization are of greatninterest for diodes and nonvolatile memory devices.n1nSpecifically,nferroelectric columnar liquid crystalline (LC) phases that featurenstable, switchable polarization along the column axis have potentialnin ultrahigh density memory devices in which ultimately a singlencolumn can function as a memory element through manipulationnof its macroscopic polarization.n2anHowever, in spite of severalnresearch efforts, stable remnant polarization in such systems hasnnot been observed.nn.
