    Sammanfattning : GaN and its alloys with Al and In belong to the group III nitride semiconductors and are today the materials of choice for efficient white light emitting diodes (LEDs) enabling energy saving solid state lighting. Currently, there is a great interest in the development of novel inexpensive techniques to fabricate hybrid LEDs combining high quality III-N quantum well (QW) structures with inexpensive colloidal nanoparticles or conjugated polymers.

    Sammanfattning : In recent decades, photoluminescence properties of single molecules and ions have opened new possibilities for studies on smaller size scales, below the light-diffraction limit. In this thesis, the advantages of such single photon emitters were harnessed and studied mainly in the field of biophysics, but also, in investigations within solid state photonics. LÄS MER

  4. 3. Protein Nanomaterials: : Functionalization, Self-assembly, and Applications

    Författare :Lei Wang; Niclas Solin; Olle Inganäs; German Salazar-Alvarez; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : As one of the major classes of materials that is relevant to biological function of our daily life, proteins are highly interesting in both biological and material science. Self-assembled protein amyloid nanostructures have been considered not only as aggregates in pathological tissue, but also as a kind of advanced one dimension materials in material science perspective due to their favorable characteristics including high aspect ratio, abundant surface charge groups, high stability, and tunable surface properties.
