Research Abstract

Ferroelectric materials with high-speed electric responses over 106 Hz have been attracted much attentions from the viewpoint of memory device applications. Most of the researches have been examined in the inorganic materials. In this work, organic-inorganic hybrid type mixed-valenced polyoxometalate compounds were examined as a new candidate of ferroelectric materials. The order-disorder transition of free electron within the cluster was applied for the dipole inversion unit for the high speed electronic response.
