  1. 1. Uncommon Ground : Urban Form and Social Territory

    Författare :Eva Minoura; Daniel Koch; Meta Berghauser Pont; Alexander Ståhle; Stephen Marshall; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; territoriality; interface; social sustainability; morphology; commons; stewardship; open space; yards; spatial analysis; Architecture; Arkitektur;

    Sammanfattning : Implicit in any urban design is a negotiation between public and private interests. Such a negotiation is articulated and made legible in the facades, fences and even more subtle edges separating this from that. A complex variety of spatial situations are produced depending on how spaces are framed, how interfaces are materialized. LÄS MER

  3. 2. Thin films of polyfluorene:fullerene blends - Morphology and its role in solar cell performance

    Författare :Cecilia Björström Svanström; Ellen Moons; Jean Manca; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Solar Cells; Polymer Blends; Morphology; Polyfluorene; PCBM; AFM; SIMS; Spin-Coating; Surface Directed Spinodal Decomposition; Physics; Fysik; Physics; Fysik;

    Sammanfattning : The sun provides us daily with large quantities of energy in the form of light. With the world’s increasing demand of electrical energy the prospect of converting this solar light into electricity is highly tempting. In the strive towards mass-production and low cost solar cells, new types of solar cells are being developed, e.g. LÄS MER

  4. 3. Thermally stable electrical contacts to 6H silicon carbide

    Författare :Nils Lundberg; Mikael Östling; Claude Jaussaud; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; I-V current -voltage ; C-V capacitance-voltage ; rectifying; ohmic; interface; silicide; carbide; epilayer; Schottky barrier height; current rectification ratio CRR ; specific contact resistivity; transmission line model TLM ; contact resistance; transfer length; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform.  Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions.
