报道了用激光全息刻写技术结合感光聚合材料体系制作介观尺度二维准周期结构(准晶).并在前期工作的基础上,研究了不同曝光量对二维空气柱孔径的影响,不同偏振对准晶结构花样的影响.实验结果显示,可以制作的二维准晶的空气柱孔径可达100nm,而且结构均匀,无缺陷面积大.用此实验系统可以制作多种花样二维甚至是三维准晶结构.目前,除激光全息刻写技术外,用其他传统精密机械加工技术来人工制作介观准晶体尚存在很大挑战性.
This paper reports the fabrication of mesoscopic two dimensional quasi-periodic structure (quasicrystal) by laser holographic lithography combined with photopolymer material system. On the basis of previous work, the effects of different exposures on the aperture of two-dimensional air column are studied. The experimental results show that the pore size of the two-dimensional quasi-crystal air column can be made up to 100nm, and the structure is uniform and the defect-free area is large.With this experimental system, a variety of two-dimensional or even three-dimensional Quasicrystal structure.At present, in addition to laser holographic writing technology, the use of other traditional precision machining technology to artificially produce mesoscopic crystals is still very challenging.
