  2. 16. Reaching for the Stars : Studies in the History of Swedish Stellar and Nebular Astronomy, 1860–1940

    Author : Gustav Holmberg; Research Policy Institute (RPI); []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; stellar astronomy; history of astronomy; astrophysics; history of modern Swedish science; scientific practice; Astronomy; Astronomi;

    Abstract : This study considers astrophysics, stellar and nebular astronomy in Sweden. Emphasis is on the role of scientific technologies and practice, and the emergence of a modern observational astronomy, supplanting classical astronomy as the most vital field of Swedish astronomy. READ MORE

  4. 17. Electronic Characterization of CVD Diamond

    Author : Saman Majdi; Carl Hemmingsson; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Diamond is a promising material for high-power, high-frequency and hightemperatureelectronics applications, where its outstanding physical propertiescan be fully exploited. It exhibits an extremely high energy gap, veryhigh carrier mobilities, high breakdown field strength, and the highest thermalconductivity of any wide bandgap material. READ MORE

  5. 18. Modelling and Degradation Characteristics of Thin-film CIGS Solar Cells

    Author : Ulf Malm; Marika Edoff; Lars Stolt; James R. Sites; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar cells; thin-film; chalcogenide; stability; characterization; modelling; simulations; finite element method; CIGS; photovoltaic module; Electronics; Elektronik;

    Abstract : Thin-film solar cells based around the absorber material CuIn1-xGaxSe2 (CIGS) are studied with respect to their stability characteristics, and different ways of modelling device operation are investigated. Two ways of modelling spatial inhomogeneities are detailed, one fully numerical and one hybrid model. READ MORE

  6. 19. Gas sensitivity of modified metal-oxide-semiconductor devices

    Author : Eva Hedborg Karlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Gas sensitive thin metal-oxide-semiconductor (MOS) structures have been used to study the effect of different modifications of the gate metal. In order to increase the selectivity of the gas sensor photoresist was used as a gas permeable membrane. READ MORE

  7. 20. Powder-metallurgical processing and phase separation in ternary transition metal carbides

    Author : Taoran Ma; Joakim Odqvist; Peter Hedström; Hans-Olof Andren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Ternary transition metal cubic carbides have high hardness and are potential carbides in cemented carbide and cermet tools, as well as hard coatings used to improve metal cutting performance. In the present work, (Ti,Zr)C, (V,Nb)C, and (V,Ta)C ternary cubic carbides were synthesized using traditional powder-metallurgical methods. READ MORE
