    Author : Reza Sanatinia; Anand Srinivasan; Andrea Fiore; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopillar; nanowires; nanophotonics; nanofabrication; III-V semiconductors; photovoltaics; second-harmonic generation; top-down approach; colloidal lithography; antireflection; modal dispersion; polarization; nanowaveguide; indium phosphide; gallium arsenide; gallium phosphide; Physics; Fysik;

    Abstract : Optical properties of semiconductor nanowires (NWs)/nanopillars (NPs), as individual or ensemble, have attracted significant research interest in recent years. Their potential applications range from solid-state lighting, photovoltaics, lasing and nonlinear optics to sensing and life sciences. READ MORE

  2. 17. Fabrication of inverse opal oxide structures for efficient light harvesting

    Author : Delphine Lebrun; Lars Österlund; Gunnar Niklasson; Vassilios Kapaklis; Herman Högström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic; inverse opal; metal oxide; opal; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Artificial opals are self-assembled face centered cubic (fcc) structures of  spherically shaped beads, which interesting applications as photonic band gap materials. Inverse opals are photonic crystals consisting of fcc paced voids of a low refractive index material imbedded in a high refractive index material. READ MORE

  3. 18. Engineered nanomaterials in in vivo and in vitro models

    Author : Laura Abariute; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

    Abstract : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. READ MORE

  4. 19. Memory Effects on Iron Oxide Filled Carbon Nanotubes

    Author : Carlos Cava; Clas Persson; Lucimara Roman; Krister Svensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory devices; Carbon Nanotubes; energy; nanotechnology; Iron Oxide;

    Abstract : In this Licentiate Thesis, the properties and effects of iron and iron oxide filled carbon nanotube (Fe-CNT) memories are investigated using experimental characterization and quantum physical theoretical models. Memory devices based on the simple assembly of Fe-CNTs between two metallic contacts are presented as a possible application involving the resistive switching phenomena of this material. READ MORE

  5. 20. Electron Transport and Charge Control in Epitaxial Graphene

    Author : Michael Winters; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Graphene monolayers and bilayers have attracted research interest in both the physics and electronic materials communities owing to their unique band structures. In a pristine monolayer, carriers travel at the Fermi velocity v_f = 1e8 cm/s and exhibit linear dispersion. READ MORE
