  2. 1. Thermal Plasmonic Metasurfaces

    Author : Gustav Edman Jönsson; Chalmers tekniska högskola; []
    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. 2. Electrochromic Plasmonic Metasurfaces for Reflective Displays

    Author : Kunli Xiong; Chalmers tekniska högskola; []
    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

  5. 3. Nanostructured electromagnetic metasurfaces at optical frequencies

    Author : Nils Odebo Länk; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; high-index nanophotonics; colloidal lithography; metasurfaces; geometric resonances; nanostructures; plasmonics;

    Abstract : Electromagnetic metasurfaces are broadly defined as optically thin layersthat are structured on the subwavelength scale. In general, metasurfacesthus consist of nanoparticles, or other kinds of ”meta-atom”, arranged insome pattern where both the individual particle sizes and the inter-particledistances are much smaller than the wavelength.

  6. 4. Conjugated polymers on plasmonic metasurfaces for high contrast electronic paper in color

    Author : Oliver Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; electrochromism; conjugated polymers; plasmonic electronic paper; PProDOT-Me2; reflective display;

    Abstract : Electronic paper is the collective name of displays that, instead of emitting light, reflect the ambient light. These displays are known to have good readability in daylight and very low power consumption. However, there is a lack of electronic paper in color with high contrast and the ability to achieve video speed. READ MORE

  7. 5. 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.
