{"product_id":"9783030030117","title":"Gyroid Optical Metamaterials: Solvent Vapour Annealing, Confined Crystallisation, and Optical Anisotropy","description":"\u003cp\u003eThis thesis explores the fabrication of gyroid-forming block copolymer templates and the optical properties of the resulting gyroid optical metamaterials, significantly contributing to our understanding of both. It demonstrates solvent vapour annealing to improve the long-range order of the templates, and investigates the unique crystallisation behaviour of their semicrystalline block. Furthermore, it shows that gyroid optical metamaterials that exhibit only short-range order are optically equivalent to nanoporous gold, and that the anomalous linear dichroism of gyroid optical metamaterials with long-range order is the result of the surface termination of the bulk gyroid morphology. \u003c\/p\u003e  Optical metamaterials are artificially engineered materials that, by virtue of their structure rather than their chemistry, may exhibit various optical properties not otherwise encountered in nature (e.g. a negative refractive index). However, these structures must be significantly smaller than the wavelength of visible light and are therefore challenging to fabricate using traditional “top down” techniques. Instead, a “bottom up” approach can be used, whereby optical metamaterials are fabricated via templates created by the self-assembly of block-copolymers. One such morphology is the gyroid, a chiral, continuous and triply periodic cubic network found in a range of natural and synthetic self-assembled systems.\u003cp\u003e\u003c\/p\u003e","brand":"Springer-Verlag New York, LLC","offers":[{"title":"Default Title","offer_id":46521892634865,"sku":"9783030030117","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9783030030117_p0.jpg?v=1765540596","url":"https:\/\/shop.barnesandnoble.com\/products\/9783030030117","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
