  2. 1. Optimization of resonant all-dielectric nanoparticles for optical manipulation and light management

    Author : Nils Odebo Länk; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; FDTD; Nanophotonics; Metasurfaces; Optical Forces; All-dielectric; Perfect Absorption; Silicon;

    Abstract : The resonant interaction between light and matter lies at the heart of nanophotonics research. In particular, nanoparticles that possess optical resonances in the visible spectral range have been avidly studied and employed for various technical and biological applications in the last two decades.

  5. 3. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano

    Author : Magnus Rahm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermodynamics; optical properties; dielectric functions; hydrides; alloy cluster expansions; alloys; nanoalloys;

    Abstract : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. READ MORE

  7. 5. Alloy Plasmonics - Fundamentals and Application in Catalysis

    Author : Christopher Tiburski; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO oxidation; nanoparticles; gold; heterogeneous catalysis; LSPR; nanoalloys; nanofabrication; light; dielectric function; palladium;

    Abstract : Alloys have for a long time been important in the development of our society; from the bronze age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, also in heterogeneous catalysis alloys are explored to develop solutions to increase activity and selectivity of chemical processes. READ MORE
