  2. 1. Laser sintered materials with Non-equilibrium structures

    Author : Bin Qian; Zhijian Shen; Germán F. de la Fuente; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser sintering; Materials; Non-equilibrium structures; microstructure; hierarchical structure; Inorganic Chemistry; oorganisk kemi;

    Abstract : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. READ MORE

  4. 2. Non-equilibrium Surfaces of Metallic Thin Films

    Author : Erik B. Svedberg; Eric E. Fullerton; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Growth and structural characterization of metallic multilayers have been performed on the Mo/W, Mo/V and Ag/Ni systems utilizing magnetron sputtering under ultra-high-vacuum deposition conditions. Structural characterization has been performed both in situ and ex situ with several electron beam probing techniques as well as x-ray diffraction. READ MORE

  5. 3. Transport theory and finite element methods for mesoscopic superconducting devices

    Author : Kevin Marc Seja; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-equilibrium superconductivity; finite element methods; unconventional superconductors; quasiclassical theory; transport theory;

    Abstract : At low temperatures, electrons in a superconductor exhibit pairing correlations that result in a macroscopic, phase-coherent ground state. This leads to peculiar electromagnetic properties such as the flow of dissipationless charge currents and expelling of external magnetic fields. READ MORE

  6. 4. Polymers in Aqueous Lubrication

    Author : Junxue An; Per M. Claesson; Martin Malsten; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lubrication; boundary lubrication; friction; surface forces; adsorption; adsorption hysteresis; non-equilibrium state; diblock copolymer; polyelectrolyte; thermoresponsive; mucin; QCM-D; ellipsometry; AFM; Kemi; Chemistry;

    Abstract : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. READ MORE

  7. 5. Electrical Characterization of Novel Insulators in Metal-Insulator-Semiconductor Structures

    Author : Anders Jauhiainen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon dioxide; MOS; Fowler-Nordheim injection; charge transport; MIS; wafer bonding; polycrystalline diamond; capacitance;

    Abstract : This thesis comprises seven papers (A-G) and an extended introduction which puts them into context within a broader field of research. The papers deal with the electrical characterization of some different insulators and interfaces encountered within the realm of silicon based microelectronics. READ MORE
