Progress in Ferroelectric Materials

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-electromechanical systems; （2） dielectric materials used for energy storage ; （ 3 ） organic ferroelectric thin films ; （4） muhiferroic which has two or more primary iron characteristics ; （5） ferroelectric resistance switching. In addition, some unresolved technical issues of ferroelectric mate- rials were summarized and the developing trends were prospected.
