  1. 11. Resonant states in modulation-doped heterostructures

    Författare :Anders Blom; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical and general theoretical physics; generation-recombination noise; THz laser; classical mechanics; relativity; quantum mechanics; statistisk fysik; gravitation; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; statistical physics; donor energies; Si SiGe quantum well; central-cell effect; impurity absorption; Fysicumarkivet A:2003:Blom; Resonant states; impurity levels;

    Sammanfattning : This thesis deals with the properties of donors placed inside or outside a heterostructure quantum well (QW). The focus of the investigation has been on the formation of resonant states, which are a hybridization of the discrete localized impurity levels and the continuous two-dimensional QW subbands.

  3. 12. Radiative lifetimes of bound excited states in anions : Measurements on long-lived metastable states in atomic anions

    Författare :Odd Magnar Hole; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : This thesis presents and discusses the results of measurements of the intrinsic lifetimes of bound excited anionic states. The results are valuable for evaluation of different theoretical models and computation methods and are compared to calculations when available. LÄS MER

  4. 13. Reaction dynamics on highly excited states

    Författare :Johanna Brinne Roos; Åsa Larson; Ioan F. Schneider; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ab initio calculations; dissociative recombination; resonant ion-pair formation; mutual neutralization; molecular electronic states; molecule-electron collisions; quantum chemistry; molecular dynamics; Chemical physics; Kemisk fysik; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Sammanfattning : In this thesis I have performed theoretical studies on the reaction dynamics in few-atom molecules. In particular, I have looked at reaction processes in which highly excited resonant states are involved. LÄS MER

  7. 15. The strategy of assistance : Swedish environmental support to the Baltic states 1991-1996

    Författare :Björn Hassler; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental cooperation; game theory; Baltic States; self-interest; rational choice; Sida; foreign aid; unitary actor; political science; modeling; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Political science; NATURAL SCIENCES;

    Sammanfattning : Sweden has provided considerable amounts of environmental assistance to the Baltic States since their regained independence. To explain the existence and character of this support program, the rationales behind the Swedish policy have to be analyzed. LÄS MER
