   Abstract : One-dimensional ZnO nanostructures have great potential applications in the fields of optoelectronic and sensor devices. Therefore, it is really important to realize the controllable growth of one-dimensional ZnO nanostructures and investigate their properties. READ MORE

5. 3. Magnetoplasmonic nanostructures

   Author : Emil Melander; Vassilios Kapaklis; Björgvin Hjörvarsson; Evangelos Th. Papaioannou; Paolo Vavassori; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Magnetism; nanostructures; plasmons; magneto-optics; magnetoplasmonics; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : Surfaces that are nanopatterned, metallic, and magnetic can support surface plasmon resonances, providing an alternative and effective way to reconfigure flat optical components. Utilising a range of near- and far-field characterisation techniques, the optical and magneto-optical properties of lithographically patterned thin magnetic films are investigated. READ MORE

6. 4. Optical properties of novel semiconductor nanostructures

   Author : Stanislav Filippov; Irina Buyanova; Weimin Chen; Galia Pozina; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Semiconductor nanostructures, such as one-dimensional nanowires (NWs) and zerodimensional quantum dots (QDs), have recently gained increasing interest due to their unique physical properties that are found attractive for a wide variety of applications ranging from gas sensing and spintronics to optoelectronics and photonics. Here, especially promising are nanostructures based on compound semiconductors, including ZnO, GaNP and GaAs/InAs. READ MORE

7. 5. Electrochromic Nickel – Tungsten Oxides : Optical, Electrochemical and Structural Characterization of Sputter-deposited Thin Films in the Whole Composition Range

   Author : Sara Green; Gunnar Niklasson; Claes-Göran Granqvist; Esteban Avendaño; Aline Rougier; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromism; Nickel oxide; Tungsten oxide; Lithium intercalation; Sputtering; Thin films; Nanostructures; Optical properties; Solid State Physics; Fasta tillståndets fysik;

   Abstract : This thesis investigates the electrochromic NixW1-x oxide thin film system, where 0 < x < 1. The thin films were deposited by reactive DC magnetron co-sputtering from one Ni and one W metal target. In addition, Ni oxide was deposited with water vapor added to the sputtering gas. READ MORE
