Structure/property relationships in advanced materials for electronics and photonics

工程多孔材料在电子和光子学技术中的应用越来越广泛。自组装胶体晶体薄膜作为一种具有多种独特光学和物理特性的简单、廉价材料，具有巨大的潜力。因此，通过消除或至少最小化我们先前研究中揭示的各种内在形成的缺陷来优化这些特性具有很大的科学和技术意义。幸运的是，对胶体光子晶体光学特性影响最大的缺陷形式是最容易解决的。它们是：i)裂纹和ii)杂质球，它们会导致部分位错和层错。本研究将制定消除或减少这些缺陷发生的策略。

Engineered porous materials are finding increasingly diverse applications in electronics and photonics technologies. Self-assembled colloidal crystal films offer great potential as simple, inexpensive materials exhibiting a variety of unique optical and physical properties. It is therefore of much scientific and technological interest to optimize these properties through the elimination, or at least the minimization, of the various intrinsically-formed defects revealed in our previous studies. Fortunately, the forms of defect having the most adverse effects on the optical properties of colloidal photonic crystals are the ones most readily addressed. These are: i) cracks and ii) impurity spheres, which give rise to partial dislocations and stacking faults. Strategies to eliminate or minimize the occurrence of these defects will be developed in this study.
