  2. 1. Toward first-principles understanding of carbonitride precipitation in steels

    Author : Dan Fors; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Steels; Coarsening; Interfaces; Peierls-Nabarro model; Diffusion; Precipitates; Density functional theory; Dislocation network; Misfit; Electronic structure;

    Abstract : The most important and widely used group of metallic alloys is steels, whichare alloys of the element iron together with carbon and usually other elementssuch as B, N, V, Nb and Cr. The strength in these alloys is closely connectedto the distribution of point defects, precipitates and grain boundaries whicheffectively act as obstacles for dislocation migration. READ MORE

  4. 2. Transition metal oxide surfaces : Surface structures and molecular interaction

    Author : Markus Soldemo; Jonas Weissenrieder; Mats Göthelid; Sarp Kaya; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Metal oxides are both corrosion products and useful materials with a wide range of applications. Two of the most used metals today are iron and copper. In this thesis, surface structures and molecular interaction with surfaces of iron oxides and copper oxides are studied using spectroscopy and microscopy methods. READ MORE

  5. 3. Electronic Structure of Transition Metal Complexes in Silicon

    Author : Per Tidlund; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; uniaxial stress; FTIR; Zeeman spectroscopy; deep levels; phonon-assisted Fano resonances; Physics; Fysik; Au; Fysicumarkivet A:1998:Tidlund; PtLi; AuLi; Pt; Transition Metals; Silicon;

    Abstract : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. READ MORE

  6. 4. Time-resolved laser spectroscopic studies of atoms, ions and Molecules

    Author : Zhongshan Li; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2000:Li;

    Abstract : Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W.
