Abstract:

Ferroelectric materials, one of the current research focuses with numbers of physical advantages such as high integration, low energy consumption and fast response, has broad application prospects in many aspects. Being combined with other physical technologies, the properties of ferroelectric materials can be significantly improved. The development  history and prevailing research profile of ferroelectric materials were introduced at first, then the performance characteristics in detail, including five mechanisms:(1) piezoelectric and its application in micro�瞖lectromechanical systems; (2) dielectric materials used for energy storage; (3)organic ferroelectric thin films; (4) multiferroic which has two or more primary iron  characteristics; (5) ferroelectric resistance switching. In addition, some unresolved technical issues of ferroelectric materials were summarized and the developing trends were prospected.��
