  1. 1. Electrochromic Plasmonic Metasurfaces for Reflective Displays

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Kunli Xiong; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasmonic; Keywords: Colorful electronic paper; Conductive polymer.;

    Abstract : Plasmonic nanomaterials provide brilliant colors that arise from the ambient light coupling to the free electrons in metals. In the Roman empire, noble metal nanoparticles were used for staining glass in Church windows and tableware. READ MORE

  2. 2. Thermal Plasmonic Metasurfaces

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Gustav Edman Jönsson; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Plasmonic materials can form viable optical absorbers that offer new possibilities for device designs as they potentially have large optical cross-sections with readily tuned spectral positions and widths. Applications for such materials include heat generation via optical absorption. READ MORE

  4. 4. Plasmonic waveguides and resonators for optical communication applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yi Song; Min Qiu; Ping Shum; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasmonic; TECHNOLOGY Electrical engineering; electronics and photonics Photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Fotonik;

    Abstract : Photonic circuits can transmit data signals in a much higher speed thanconventional electronic circuits. However, miniaturization of photonic circuitsand devices is hindered by the existence of light diffraction limit. A promisingsolution to this problem is by exploiting plasmonic systems for guiding andmanipulating signals at optical frequencies. READ MORE

  5. 5. Plasmonic Nanospectrocopy of Individual Nanoparticles - Studies of Metal-Hydrogen Interactions and Catalysis

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Svetlana Alekseeva; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; grain boundary; metal-hydrogen interactions; plasmonic sensors; single particle spectroscopy; palladium nanoparticles and nanocrystals; localized surface plasmon resonance; hole-mask colloidal lithography; nanocatalysts; shrinking-hole colloidal lithography; plasmonic nanospectroscopy; dark field scattering spectroscopy; nanoscale effects;

    Abstract : Localized surface plasmon resonance (LSPR) is the phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light used for the excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. READ MORE
