补充资料：热释电材料
| 热释电材料 pyroelectric material 具有自发极化特性的晶体材料。自发极化是指由于物质本身的结构在某个方向上正负电荷中心不重合而固有的极化。一般情况下，晶体自发极化所产生的表面束缚电荷被吸附在晶体表面上的自由电荷所屏蔽，当温度变化时，自发极化发生改变，从而释放出表面吸附的部分电荷。晶体冷却时电荷极性与加热时相反。热释电材料是一种压电材料，是不具有中心对称性的晶体。具有热释电特性的材料有上千种，但广泛应用的不过十几种，主要有硫酸三苷肽、锆钛酸铅镧、透明陶瓷和聚合物薄膜。热释电材料在工业上可用作红外探测器件，热摄像管并在国防上有某些特殊用途。其优点是不用低温冷却，但灵敏度比相应的半导体器件低。 |
