  1. 1. Thermally and Optically Excited Electron Transport in Semiconductor Nanowires

    Författare :I-Ju Chen; Fasta tillståndets fysik; []
    Nyckelord :Fysicumarkivet A:2018:Chen;

    Sammanfattning : This thesis explores the transport of thermally and optically excited electrons invarious nanowire structures. On one hand, electrons are thermally excited when thetemperature is nonzero, and the thermal energy help them surmount energy barriersthat are present in the material. LÄS MER

  3. 2. Bi-based high Tc superconductors and enhancement of critical current density

    Författare :Shi-ju Guo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : Basic bulk high temperature superconductors in the Bi-Sr-Ca-Cu-O system and the BiPb-Sr-Ca-Cu-O system were prepared through the solid state reaction route and the coprecipitation method. The formation of 110 K phase promoted by partial Pb substitution for Bi was studied. Effects of heat treatment on 110K phase formation were studied. LÄS MER

  4. 3. Neuronal mechanisms of feedback postural control

    Författare :Li-Ju Hsu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postural control; equilibrium; body configuration; reticulospinal neurons; stretch receptor neurons; galvanic vestibular stimulation; artificial feedback; locomotion; spinalization; rabbit; lamprey;

    Sammanfattning : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. LÄS MER

  7. 5. Essays on Female Policymakers and Policy Outcomes

    Författare :Li-Ju Chen; Per Pettersson-Lidbom; Lena Edlund; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; female legislator; political economy; distance to the technological frontier; gender quotas; policy outcomes; Economics; Nationalekonomi; Economics; nationalekonomi;

    Sammanfattning : The thesis consists of three papers, summarized as follows. "Female Policymakers and Educational Expenditures: Cross-Country Evidence" This paper investigates the influence of women in politics on decision-making using public educational expenditures as the outcome of interest.
