  2. 1. Structural and Magnetic Properties of Fe/Co (001) and Fe/V (001) Superlattices

    Author : Peter Blomqvist; Jens Birch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Tunna filmer; kristallin struktur; magnetism; järn; kobolt; vanadin; Physics; Fysik; fysik; Physics;

    Abstract : The structural and magnetic properties of Fe/Co (001) and Fe/V (001) superlattices have been investigated. The thin film structures were deposited on MgO (001) substrates using a four source ultra-high-vacuum based sputtering equipment. READ MORE

  4. 2. Structural impact on some physical properties of cellulose-based films

    Author : Malin Nejström; Magnus Norgren; Håkan Edlund; Ida Svanedal; Bo Andreasson; Lars Evenäs; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Cellulose is a natural material that can be used both in its original form and as a building block for creating new types of materials. This work focused on regenerated cellulose (RC) and cellulose acetate butyrate (CAB) in which the hydroxyls on the cellulose backbone were substituted with ester groups. READ MORE

  5. 3. Optical studies of AlN and GaO based nanostructures using Mueller matrix spectroscopic ellipsometry

    Author : Samiran Bairagi; Kenneth Järrendahl; Ching-Lien Hsiao; Bruno Gallas; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GLAD; MMSE; PVD; III-nitrides; Oxides; Anisotropy; Bandgap;

    Abstract : This thesis explores the diverse optical properties manifested when light interacts with various materials, with an emphasis on circular polarization- and bandgaprelated phenomena. The studies in this work are centered around Mueller matrix spectroscopic ellipsometry, with the objective of synthesizing and characterizing nanostructured and high-quality thin films to expand our understanding of the optical properties arising from their underlying structure and electronic transitions, respectively.

  6. 4. Synthesis of nanoporous Ca3Co4O9 thin films for flexible thermoelectrics

    Author : Binbin Xin; Per Eklund; Biplab Paul; Niclas Solin; Tomas Nyberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : During energy generation, transportation and usage, large amounts of energy are lost as waste heat. With increasing energy consumption and environmental issues, exploiting this waste heat has drawn extensive attention. READ MORE

  7. 5. Synthesis and Characterization of Transition Metal Diborides

    Author : Jimmy Thörnberg; Johanna Rosén; Per Persson; Helmut Riedl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DCMS; HiPIMS; Titanium Diboride; Titanium Aluminum Diboride; Chromium Diboride; Microstructure; Hardness; Oxidation Resistance;

    Abstract : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. READ MORE
