项目摘要

We have developed optical, dielectric and piezoelectric properties by making use of engineered domain configuration and their device by using relaxor ferroelectric solid solution single crystals as follows ; Relaxor ferroelectric solid solution single crystal, device, and method of using device; a method of using a device that uses a relaxor ferroelectric solid solution single crystal, wherein the relaxor PMN-PT solid solution single crystal is capable of making transitions, at temperatures below the Curie temperature between a first state which has a high permittivity and blocks optical transmission and a second state which has a low permittivity and allows optical transmission, and the relaxor ferroelectric solid solution single crystal undergoes a transition to the second state if an electric field above a threshold is applied in the first state and undergoes a transition to the first state if it heated to or above the Curie temperature in the second states. Such memory effect and optical valve together with electric field induced transition from high to low permittivity in the relaxor ferroelectrics are very important for device applications. In addition, superior piezoelectric properties in the rhombohedral (001) plate in PMN-PT relaxor ferroelectric solid solution single crystal under loading play important role for IT optical and mechatronic device application. We discovered that relaxor ferroelectric single crystals reveal three optical, dielectric and piezoelectric functions at a same time, and succeeded occurring of their functions with one element, at the same time, by making use of engineered domain structure in the rhombohedral (001) plate in relaxor ferroelectric solid solution single crystals.
我们通过使用弛豫铁电固溶体单晶,利用工程畴结构及其器件开发了光学、介电和压电性能,如下:弛豫铁电固溶体单晶、器件和使用器件的方法;一种使用弛豫铁电固溶体单晶的器件的使用方法,其中所述弛豫PMN-PT固溶体单晶能够在低于居里温度的温度下在具有高介电常数并且阻挡光传输的第一状态和具有低介电常数并且允许光传输的第二状态之间进行转变,并且如果在第一状态中施加高于阈值的电场,则弛豫铁电固溶体单晶经历到第二状态的转变,并且如果在第二状态中被加热到居里温度或高于居里温度,则弛豫铁电固溶体单晶经历到第一状态的转变。弛豫铁电体中的这种记忆效应、光阀效应以及电场诱导的介电常数从高到低的转变对于器件应用是非常重要的。此外,PMN-PT弛豫铁电固溶体单晶中菱面体(001)板在加载条件下的上级压电性能对IT光机电器件的应用具有重要意义。利用弛豫铁电固溶体单晶中菱面体(001)板中的工程畴结构,发现弛豫铁电单晶同时具有光学、介电和压电三种功能,并成功地实现了一种元素同时具有三种功能。
