    Sammanfattning : One possibility to partially satisfy the ever-increasing energy needs of modern society, without compromising the Earth’s environment through e.g. global warming, consists in harvesting solar energy and storing it as hydrogen produced from water splitting. This can potentially be achieved on a large scale using photoelectrochemical (PEC) cells. LÄS MER

  3. 17. Simulations of directionality effects and optical forces in plasmonic nanostructures

    Författare :Vladimir Miljkovic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Comsol multiphysics; optical forces; nanoparticles; nanowires; DDA; surface plasmons; Green’s function; Mie theory;

    Sammanfattning : With the rapid development of nanoscience and nanotechnology, surface plasmonics based on metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for optical and sensor applications. At the nanoscale, the physical and chemical properties of metal particles, especially their optical properties, strongly depend on size and shape, as well as on the surrounding media and structures.

  5. 19. Nanoplasmonic Structures for Bio/Chemo Sensing

    Författare :Tomas Rindzevicius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface-enhancement; biorecognition; nanostructures; surface plasmons; nanoholes.; biosensing;

    Sammanfattning : Localized surface plasmon resonances (LSPR's) in noblemetal nanostructures are sensitive to refractive index changes close to the metal surface, and the LSPR's can therefore be utilized to sense molecular binding reactions. This thesis focuses on fundamental properties and proof-of-principle sensing studies of nanoplasmonic structures relevant for molecular detection. LÄS MER
