  1. 16. Plasmonic Nanostructures for Optical Absorption Engineering and Hydrogen Sensing

    Författare :Carl Wadell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; metal hydride; alloy nanoparticles; palladium; absorption engineering; plasmon enhanced chemistry; nanoplasmonic sensing; nanoparticle size effects; localized surface plasmon resonance; hydrogen sensing;

    Sammanfattning : Nanoplasmonics concerns the interactions between light and metal nanoparticles. In this thesis nanoplasmonics is used in two different ways: i) to control and enhance light absorption, and ii) for optical hydrogen sensing. LÄS MER

    Författare :Markus Schwind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Sammanfattning : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. LÄS MER

  4. 18. Nanoparticle plasmon influence on the charge carrier generation in solar cells

    Författare :Carl Hägglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; solar cells; finite element method; nanoparticle plasmons; photovoltaics; nanofabrication; Si; dye sensitized solar cells; localized surface plasmon resonances;

    Sammanfattning : Global warming is a potential threat to life on earth and to human society. It is by much evidence linked to the extensive use of fossil fuels in our present energy system. Replacing the fossil fuels by alternative sources of energy poses a tremendous challenge for mankind, but is not at all undoable. LÄS MER

  5. 19. Nanofabrication of Single Electron Transistors and Evaluation of Miniature Biosensors

    Författare :Linda G. M. Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturization; nanoparticles; impedance; single electron tunneling; biosensors; surface plasmon resonance;

    Sammanfattning : This thesis deals with miniaturization in two different fields: electronics and biosensing. The first part deals with fabrication and measurements of two nanoscale structures - a self-assembled single electron transistor and a (potential) single junction device. LÄS MER

  7. 20. Towards Functional Nanopores Using Polymers

    Författare :Gustav Emilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface plasmon resonance; protein adsorption; poly ethylene glycol ; nanopores.; grafting; poly N-isopropylacrylamide ; polymer brush;

    Sammanfattning : In nature there are several examples of nanometer sized gateways able to control the passage of molecules and other substances with remarkable precision. This has inspired research in trying to create nanoscale openings which resemble such gateways. LÄS MER
