  2. 21. Material characterization for magnetically confined fusion : Surface analysis and method development

    Author : Petter Ström; Marek Rubel; Per Petersson; Thierry Loarer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The dream of abundant clean energy has brought scientists and laypeople alike to ponder the possibilities of nuclear fusion since it was established as the energy source of the stars in 1939. Starting from the mid-twentieth century, significant effort has been put into overcoming the technological challenges related to the construction of a power plant, but initial optimism has faded somewhat due to a notable absence of practical outcomes.

  4. 22. Physical Properties and Structural stability of carbon nanotubes under extreme conditions

    Author : Maxime Noël; Roberts Joffe; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics; Physics; Fysik;

    Abstract : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. READ MORE

  5. 23. Densities and Sizes of Self-assembled Quantum Dots Grown by MOVPE

    Author : Jonas Johansson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembled quantum dots; Metal organic vapour phase epitaxy; Physics; Stranski-Krastanow; Fysicumarkivet 2000:Johansson; Halvledarfysik; Semiconductory physics; Fysik;

    Abstract : This thesis is based on results concerning the formation of semiconductor self-assembled quantum dots. The quantum dots have been grown by metal organic vapour phase epitaxy in the Stranski-Krastanow growth mode. READ MORE

  6. 24. Epitaxial Growth and Design of Nanowires and Complex Nanostructures

    Author : Kimberly Dick Thelander; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural science; III-V Semiconductor Materials; Fysik; Kondenserade materiens egenskaper:struktur; phase equilibria; crystallography; thermal and mechanical properties; Condensed matter:stucture; egenskaper termiska och mekaniska ; kristallografi; fasjämvikt; Naturvetenskap; Physics; Nanowires; Vapour Phase Epitaxy; Semiconductory physics; Halvledarfysik;

    Abstract : This thesis describes the epitaxial growth of III-V semiconductor nanowires using Au seed particles, and the design of more complex three-dimensional branched structures from these wires. Growth was performed by metallorganic vapour phase epitaxy, in which precursor molecules for the semiconductor material components are introduced in a low-pressure vapour. READ MORE

  7. 25. Imaging materials with intermodulation : Studies in multifrequency atomic force microscopy

    Author : Daniel Forchheimer; David Haviland; Arvind Raman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomic force microscopy; nonlinear dynamics; frequency mixing; force reconstruction; Fysik; Physics;

    Abstract : The Atomic Force Microscope (AFM) is a tool for imaging surfaces at the microand nano meter scale. The microscope senses the force acting between a surfaceand a tip positioned at the end of a micro-cantilever, forming an image of the surface topography. READ MORE
