3. 2. Cathodoluminescence Studies of Quantum Structures and III-V nitrides

   Författare :Anders Petersson; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AlGaN; Fysik; Physics; GaN-AlGaN; single dot spectroscopy; InP-GaInP; Stranski Krastanow; quantum dots; quantum wires; low-dimensional structures; InAs-GaAs; III-V nitride; Cathodoluminescence; III-V semiconductors; Fysicumarkivet A:1999:Petersson;

   Sammanfattning : Characterization of low-dimensional semiconductor structures is a challenging task. The thesis is based on experiments, using cathodoluminescence (CL) as a tool for characterization. The high spatial resolution and the possibility of spectroscopy of small structures make CL one of the most powerful techniques for these types of investigations. LÄS MER

4. 3. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution

   Författare :Anders Petersson; KTH; []
   Nyckelord :Cemented carbides; Sintering; Constitutive relations; Microstructure; Densification; Modelling;

   Sammanfattning : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. LÄS MER

5. 4. Ion Beam Analysis of First Wall Materials Exposed to Plasma in Fusion Devices

   Författare :Per Petersson; Göran Possnert; Anders Hallén; Marek Rubel; Eduardo C. Alves; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion beam analysis; Microbeam; Plasma wall interaction; Deuterium; Beryllium; Carbon fibre composites; Divertor; Nuclear reaction analysis; Helium-3; Plasma physics with fusion; Plasmafysik med fusion; Ion Physics; Jonfysik;

   Sammanfattning : One major step needed for fusion to become a reliable energy source is the development of materials for the extreme conditions (high temperature, radioactivity and erosion) caused by hot plasmas. The main goal of the present study is to use and optimise ion beam methods (lateral resolution and sensitivity) to characterise the distribution of hydrogen isotopes that act as fuel. LÄS MER
