  1. 1. Growth and characterization of TiN/SiNx multilayer thin films

    University dissertation from Luleå tekniska universitet

    Author : Hans Söderberg; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Abstract : The demands from industry for higher cutting speeds, feeding rates, and reduction of the use of cooling agents during turning and milling operations are increasing. Consequently the requirements on the cutting inserts are increasing and new advanced coatings that can withstand the higher temperatures and larger loads are highly sought after. READ MORE

  2. 2. Aberration-Corrected Analytical Electron Microscopy of Transition Metal Nitride and Silicon Nitride Multilayers

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Amie Fallqvist; Per Persson; Lars Hultman; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Two multilayer thin films have been studied: TiN/SiNx and ZrN/SiNx. A double-corrected transmission electron microscope (TEM) was utilized for imaging and spectroscopy. Imaging was carried out in scanning mode (STEM) for all samples. READ MORE

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Axel Flink; Lars Hultman; Paul Mayrhofer; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical transmission electron microscopy; Arc; Sputtering; Hard coatings; Multilayer Cutting inserts; analytisk transmissionselektronmikroskopi; ytbeläggningar; skärande; bearbetning; Ti-Si-N; arcförångning; sputtring; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Abstract : Utvecklingen inom materialforskningen går mot att framställa avancerade material vilka är skräddarsydda för olika tillämpningar. Detta har medfört att det blir allt mer populärt att belägga ytor med ett eller flera tunna lager med syfte att förbättra materialegenskaperna. READ MORE

    Abstract : Metastable (Ti,Si)N alloy and TiN/SiNx multilayer thin solid films as well as SiNx/TiN surfaces have been explored. Cubic Ti1-xSixN (0≤x≤0. READ MORE

  5. 5. Characterization and Analysis of Surface Passivations and Gate Insulators for AlGaN/GaN Microwave HFETs

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Martin Fagerlind; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HFET; passivation characterization; passivation; AlGaN GaN heterostructure;

    Abstract : The large bandgap of gallium nitride (GaN) and aluminum gallium nitride (AlGaN) offers an inherently high intrinsic breakdown field. When the materials are joined into the AlGaN/GaN heterostructure a 2-dimensional electron gas (2DEG) with a high electron density as well as high electron mobility is generated. READ MORE
