We demonstrate a new and simple method of precisely fabricating defects in three-dimensional (3D) CdS macroporous photonic crystals (PCs) with a variable pressure scanning electron microscope. Well-defined point defects, not only vacancies but also an impurity (a reduced-size sphere), were directly fabricated by electron-beam irradiation under a gas atmosphere. This provides a convenient and straightforward method of introducing various designed defects into 3D PCs for photonic-band-gap-based applications.
我们展示了一种利用可变压力扫描电子显微镜精确制造三维(3D)硫化镉大孔光子晶体(PCs)缺陷的全新简单方法。在气体气氛下通过电子束辐照直接制造出了定义明确的点缺陷,不仅有空位,还有杂质(尺寸减小的球体)。这为基于光子带隙的应用将各种设计缺陷引入3D光子晶体提供了一种便捷直接的方法。
