  1. 1. Chemical vapor deposition of hard coatings : Development of W(C,N) coatings for cemented carbide and TiN deposition on a CoCrFeNi substrate

    Författare :Katalin Böőr; Mats Boman; Markku Leskelä; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : There is a constant need for cutting tool material development to be able to machine new materials and improve the metal cutting efficiency. Inserts of indexable cutting tools usually consist of WC-Co cemented carbide (cc) with μm thick layers of ceramic coatings. LÄS MER

  3. 2. A Quantum Chemical Exploration of SiC Chemical Vapor Deposition

    Författare :Pitsiri Sukkaew; Örjan Danielsson; Erik Janzén; Olle Kordina; Lars Ojamäe; Raymond A. Adomaitis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : SiC is a wide bandgap semiconductor with many attractive properties. It hasattracted particular attentions in the areas of power and sensor devices as wellas biomedical and biosensor applications. This is owing to its properties suchas large bandgap, high breakdown electric field, high thermal conductivitiesand chemically robustness. LÄS MER

  4. 3. Simulations of Silicon Carbide Chemical Vapor Deposition

    Författare :Örjan Danielsson; Erik Janzén; Anne Henry; Michel Pons; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. LÄS MER

  5. 4. Thin Film Synthesis of Nickel Containing Compounds

    Författare :Erik Lindahl; Jan-Otto Carlsson; Jens Birch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical Vapor Deposition; CVD; Atomic Layer Deposition; ALD; Nickel nitride; Nickel oxide; Nickel; Epitaxy; multilayer; Thin film; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Sammanfattning : Most electrical, magnetic or optical devices are today based on several, usually extremely thin layers of different materials.  In this thesis chemical synthesis processes have been developed for growth of less stable and metastable layers, and even multilayers, of nickel containing compounds.

  7. 5. Conjugated Polymer-based Conductive Fibers for Smart Textile Applications

    Författare :Tariq Bashir; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electro-active fibers; poly 3; 4-ethylenedioxythiophene PEDOT ; viscose; polyester; chemical vapor deposition CVD process; electrical characterizations; smart textiles; stretch sensor; Organic Electronics; Smart Textiles; textile yarns; Textiles and Fashion General ; Textil och mode generell ;

    Sammanfattning : Electrically conductive or electro-active fibers are the key components of smart and interactive textiles, which could be used in medical, sports, energy, and military applications in the near future. The functionalization of high-performance textile yarns/fibers with conjugated polymers can produce conductive fibers with better electro-mechanical properties, which is difficult with commonly used spinning techniques.
