Definition and Scope:The Priority Programme aims at the investigation of photonic properties of materials with deliberately introduced and controlled structural and/or compositional disorder from a fundamental scientific perspective. Recent developments in this emerging research field showed that breaking periodicity opens fabrication routes for novel materials and devices with desired, unusual and unforeseen optical properties.For the projects it is mandatory to identify design rules for artificial synthesis or fabrication of photonic architectures for the visible and NIR wavelength range with tailored disorder, in combination with one of the following research directions:• identification and characterisation of biological blueprints showing photonic nano-structures with properties originating from disorder,• development of theoretical and numerical tools to model structures with tailored disorder,• development of novel structures with properties that rely on tailored disorder.The Priority Programme’s final goal is to comprehend, artificially design and fabricate a novel class of advanced photonic materials and custom-made devices for a variety of applications, the performance of which is related to tailored disorder within 2-D/3-D architectures.However, projects in this programme shall not be concerned with metamaterials, individual plasmonic antennas or material systems, such as conventional photonic crystals, that derive their defining properties primarily from effective materials or their periodicity, and whose probably present intrinsic disorder is rather negligible or undesired and just happens due to arbitrary fabrication inaccuracies. Material systems that are not concerned with photon transport but other wave-like transport or scattering phenomena such as electron transport, sound waves, matter waves or spin waves regardless of whether they occur in ordered or disordered media shall also be excluded. Albeit chemical functionalisation to enable self-assembly aspects in the fabrication of disordered photonic structures shall be considered a valid topic to be addressed within this Priority Programme, self-assembly based on DNA-functionalisation shall be excluded.The programme focusses on the generation of different types of tailored disorder in materials using a methodical science- and engineering approach in which various natural science and engineering science disciplines cooperate, by using e.g. inspiration from biological systems, results from physics, chemical approaches and validation from modelling, together with materials science and engineering achievements. Priority will be given to projects that combine at least two of the specified scientific disciplines to further promote the strongly desired overall interdisciplinary approach expressed in this programme.
