摘要： A film is presented having super-pyroelectric properties. The film comprises nano-sized grains being in a ferroelectric phase and having at least three different crystallographic variants defining at least two polycrystalline macro-domains. The film is shaped to define at least one film region with the macro-domains of a predetermined shape and different orientations of crystallographic axes with respect to the film's surface, thereby enabling to apply a temperature change to the film to induce movement of the polycrystalline macro-domains boundaries enabling super-pyroelectric properties.
摘要翻译： 呈现具有超热电性质的膜。 该膜包含在铁电相中的纳米尺寸的晶粒，并且具有限定至少两个多晶宏观域的至少三种不同的晶体变体。 该膜被成形为限定具有预定形状的宏观域和相对于膜表面的结晶轴的不同取向的至少一个膜区域，从而能够对膜施加温度变化以引起多晶宏观的移动 - 具有超级热电性能的界限。
