Multi-hierarchical amorphous metamaterials

用自下而上的方法制造并利用自组织机制制造的超材料将使新的应用成为可能。它们将完美地补充过去用自上而下技术制造的超材料。这些材料是证明许多基本和突破性性能的决定性因素，但对于所有需要真正散装材料的设备来说，它们只是边缘用途。然而，在新生的自组装超材料领域，在大多数情况下，孤立的元原子是令人感兴趣的;或者最多是被充分稀释的元原子，以至于任何相互作用都可以被忽略。为了观察实现功能器件所必需的色散效应，需要解除这一限制。材料迫切需要由密集堆积的元原子组成，其中元原子之间的耦合是显着的。自组织自下而上的超材料是一种重要的超材料，其中超原子间的耦合是一个重要的研究领域。如果最终能够在单个元原子之间的相互作用中实现强耦合机制，那么将出现一种在纳米尺度上驯服光的全新方法。它将允许新的功能，其中非线性效应可以增强几个数量级，其中出现强手性响应，或者其中光谱响应可以在非常窄的频率空间内突然变化。聚集在一起建议这个项目的合作伙伴都有各自的互补专业知识。然而，必须将它们提供的专业知识结合起来，才能实现应用程序中制定和描述的目标。在这个跨学科的项目中，我们希望设计，制造，并在远场和近场的自组装自下而上的超材料的线性和非线性特性的特征。我们将设计选定的应用程序，以证明在纳米尺度上对光-物质相互作用进行前所未有的控制的承诺。

Metamaterials made with bottom-up approaches and fabricated while exploiting mechanisms of self-organisation would enable novel applications. They would perfectly complement metamaterials fabricated in the past with top-down technologies. These materials were decisive to prove many basic and groundbreaking properties, but they are only of marginal use for all devices were truly bulk materials are required. In the nascent field of self-assembled metamaterials, however, in most cases isolated meta-atoms were of interest; or at most meta-atoms sufficiently diluted such that any interaction could have been neglected. To observe the dispersive effects necessary to achieve functional devices, this limitation needs to be lifted. Materials are urgently required that consist of densely packed meta-atoms where the coupling among meta-atoms is significantly. Self-organized bottom-up metamaterials were the coupling among meta-atoms is important have never been studied. If eventually a strong coupling regime in the interaction among individual meta-atoms can be achieved, an entire new approach to tame light at the nanoscale will emerge. It will allow novel functionalities, where nonlinear effects can be enhanced by orders of magnitude, where a strong chiral response emerges or where the spectral response can change abruptly across a very narrow frequency space. The partners that came together to suggest this project all have an individual and complementary expertise. The expertise they provide, however, has to be combined to reach the goals formulated and described in the application. In this interdisciplinary project we wish to design, to fabricate, and to characterize in the far- and in the near-field the linear and nonlinear properties of self-assembled bottom-up metamaterials. We will engineer selected applications to prove the promise of an unprecedented control over light-matter interaction at the nanoscale.
