中国科学院北京纳米能源与系统研究所的研究人员研制出了利用压电光子学效应实现动态应力成像的高分辨率、快速响应的功能器件,并将其成功应用于手写电子签名系统。压电光子学效应通过压电半导体在压力作用下产生的内部压电势调节能带结构,有利于激发掺杂引入的发光中心,从而实现应力作用下的光发射过程。研究人员基于 Researchers at Beijing Institute of Nano-Energy and Systems, Chinese Academy of Sciences, have developed high-resolution, fast-responding functional devices that use dynamic piezoelectric imaging for dynamic stress imaging and have successfully applied them to handwritten electronic signature systems. Piezoelectric photonic effect through the piezoelectric semiconductor under pressure generated by the internal piezoelectric potential to adjust the band structure is conducive to stimulate the introduction of doped light-emitting center, in order to achieve the role of stress under the light emission process.
