  1. 1. Essays on Fiscal Policy, Public Debt and Financial Development

    Författare :Alfredo Schclarek Curutchet; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; private consumption; Ekonomisk planering; Handel; Economic planning; imperfect information; Trade; financial development; economic growth; capital accumulation; productivity growth; private savings rate; vertical innovation; horizontal innovation; industry diversification; public debt; external debt; developing countries; taxation; government expenditure; fiscal policy;

    Sammanfattning : This thesis consists of three distinct articles that can be read separately. Each one has been awarded a chapter of its own. The independence of these chapters should not be taken as meaning that they are unrelated. Besides belonging all to the subfield of macroeconomics, they share the common feature of being inherently economic policy oriented. LÄS MER

  3. 2. Essays on job turnover, productivity and state-local finance

    Författare :Linda Andersson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; risk-sharing; intergovernmental transfers; international competition; job turnover; local and regional governments; openness; R D; spillover; structural change; taxes; TFP growth; vertical external effects;

    Sammanfattning : This thesis consists of four self-contained papers on job turnover, productivity and state- local finance.Paper [I] deals with the determinants of the rate of job turnover defined as the change in distribution of employment between and within industries in Swedish manufacturing.

  4. 3. Single Junction and Tandem Junction Nanowire Solar Cells

    Författare :David Alcer; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire solar cell; GaInP; InP; Tandem junction; Vertical processing;

    Sammanfattning : Solar cells based on silicon are successfully harvesting solar energy in established and increasingly widespread solar panels. However, their efficiency is limited by the Shockley–Queisser limit. For certain applications where high efficiency is the key figure of merit, the use of multi-junction solar cells is desirable.

  5. 4. Nonlinear Dust Particle Dynamics and Collective Effects in Complex Plasmas

    Författare :Gianfranco Sorasio; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Complex Dusty Plasmas; Self excited; Nonlinear; Forced Oscillations; Electrostatic Instabilities in current-carrying magnetoplasmas; Cross-field instabilities in magnetized dusty plasmas; Dust Acoustic Waves; Electrostatic Dust Cyclotron Waves; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Theoretical studies of dusty plasmas have been performed by focusing attention principally on collective phenomena and on grain motion. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. LÄS MER

  7. 5. Optically pumped semiconductor disk lasers for high-power wide wavelength tuning

    Författare :Carl Borgentun; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; beam characterization; design; high power; wavelength tuning; Semiconductor laser; gain measurements; vertical-external-cavity surface-emitting laser; optically pumped semiconductor disk laser;

    Sammanfattning : In this work I present and verify a strategy that makes it possible to change the wavelength, or color, of an external cavity semiconductor laser over a very large range. This is achieved by a careful design and thorough optimization of the active component — the gain element of the laser. LÄS MER
