  1. 1. Interphases in Polymer Blends

    Författare :Hans Eklind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morphology; interdiffusion; compatibilization; characterization; interfacial interaction; mobility; micromechanical transition; dynamic mechanical properties; interphase; polymer blend;

    Sammanfattning : The blending of polymers is a useful means of combining and improving the properties of already existing polymers in the development of new materials at reasonable cost. As most polymers are immiscible with each other, heterogeneous blends are often formed. The properties of such blends are strongly determined by the properties of the interphase. LÄS MER

  3. 2. Low-frequency noise in high-k gate stacks with interfacial layer engineering

    Författare :Maryam Olyaei; Bengt Gunnar Malm; Paolo Pavan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; high k; 1 f noise; low-frequency noise; number fluctuations; mobility fluctuat ions; traps; interfacial layer; TmSiO; Tm 2O3; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The rapid progress of complementary-metal-oxide-semiconductor (CMOS) integrated circuit technology became feasible through continuous device scaling. The implementation of high-k/metal gates had a significantcontribution to this progress during the last decade. However, there are still challenges regarding the reliability of these devices.

  4. 3. Simulation of diffusional processes in alloys : techniques and applications

    Författare :Henrik Strandlund; John Ågren; John Morral; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Kirkendall effect; Phase transformations; Random walk; Solute drag; Interfacial mobility; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : This thesis concerns computer simulation of diffusional processes in alloys. The main focus is on the development of simulation techniques for diffusion in single-phase domains, but also diffusion controlled phase-transformations and interfacial processes are discussed.

    Sammanfattning : Epitaxially grown SiGe(C) materials have a great importance for many device applications. In these applications, (strained or relaxed) SiGe(C) layers are grown either selectively on the active areas, or on the entire wafer. LÄS MER

  7. 5. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation

    Författare :Apurve Saini; Max Wolff; Vassilios Kapaklis; Pietro Tierno; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Soft matter; Colloids; Magnetic nanoparticles; Ferrofluid; Solid-liquid interface; Neutron reflectometry; Electrical sensing; Microcontact; Materiefysik; Physics of Matter;

    Sammanfattning : Self-organisation is the key route for assembling colloidal particles into well-defined structures. Decisive for this are the interactions between the constituents, which are amongst others steric, electrostatic or magnetic. LÄS MER
