  2. 1. Advanced TCAD Simulations and Characterization of Semiconductor Devices

    Author : Tony Ewert; Jörgen Olsson; Marcel Pelgrom; Uppsala universitet; []
    Keywords : Electronics; MOSFET; RDF; random dopant fluctuation; asymmetric; parametric mismatch; TCAD; compact modeling; fluctuation model; Elektronik;

    Abstract : Today, micro- and nano-electronic devices are becoming more complex and advanced as the dimensions are shrinking. It is therefore a very challenging task to develop new device technologies with performance that can be predicted. READ MORE

  4. 2. Borehole Thermal Energy Storage Systems for Storage of Industrial Excess Heat : Performance Evaluation and Modelling

    Author : Emil Nilsson; Patrik Rohdin; Maria Andersson; Mathias Cehlin; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Improving industrial energy efficiency is considered an important factor in reducing carbon dioxide emissions and counteract climate change. For many industrial companies in cold climates, heat generated at the site in summer will not be needed to fulfil the site heat demand during this time, and is thus removed to the outdoor air.

  5. 3. On Specifying and Estimating Economic Growth as a Spatial Process : Convergence, Inequality, and Migration

    Author : Martin E. Gustafsson; Roger Bivand; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Economic geography; economic growth; regional convergence; migration; spatial statistics; spatially correlated errors; geographical dependence; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Abstract : This thesis includes three self-contained papers. The first paper considers the effect of geographically dependent observations on cross-sectional growth convergence and proposes a way of decomposing the level of technology taking into account geographical variation in growth rates.

  6. 4. Multi-fastener single-lap joints in composite structures

    Author : Johan Ekh; Dan Zenkert; Michael McCarthy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

    Abstract : This thesis deals with composite joints. Designing such joints is more difficult than metallic joints due to the mechanical properties of composite materials. Composites are anisotropic and have a limited ability of yielding. READ MORE

  7. 5. Quasi-phase matched devices in Rb-doped KTiOPO4: counterpropagating nonlinear interactions, domain dynamics, and waveguides

    Author : Patrick Mutter; Carlota Canalias; Christopher Phillips; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Abstract Nonlinear interactions involving counterpropagating photons are gaining much attention in classical and quantum optics due to their unique properties that are very difficult, if not impossible, to realize in conventional co-propagating three-wave mixing. However, the large phase mismatch between the interacting waves demands an unnaturally large material birefringence or high-quality quasi-phasematched (QPM) devices with sub-µm periods. READ MORE
