  2. 21. Bilayer Light-Emitting Electrochemical Cells for Signage and Lighting Applications

    Author : E. Mattias Lindh; Ludvig Edman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Light-emitting electrochemical cell; Signage; Display; Luminescent line art; Inkjet printing; Direct-write printing; fysik; Physics; Electronics; elektronik;

    Abstract : Artificial light surrounds us in a manifold of shapes. It is mainly utilized for illumination, but also for graphical communication of complex and evolving messages and information, among other things. It can be generated in different ways with incandescent lamps and fluorescent tubes constituting two common examples. READ MORE

  4. 22. Electronic Structure and Film Morphology Studies of PTCDI on Metal/Semiconductor Surfaces

    Abstract : Quantum dots, also known as artificial atoms, are created by tightly confining electrons, and thereby quantizing their energies. They are important components in the emerging fields of nanotechnology where their potential uses vary from dyes to quantum computing qubits. Interesting properties to investigate are e.g. READ MORE

  6. 24. Vertical III-V Semiconductor Devices

    Author : Tomas Bryllert; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Halvledarfysik; Semiconductory physics; heterostructure barrier varactor frequency multiplier; field effect transistor; resonant tunneling; artificial molecule; terahertz; nanowire; Quantum dots;

    Abstract : This thesis is based on three projects that deal with vertical III-V semiconductor devices. The work spans over basic research as well as more applied aspects of III-V semiconductor technology. All projects have in common that they rely on advanced epitaxial growth to form the starting material for device fabrication. READ MORE

  7. 25. Doping of Semiconductor Nanowires

    Author : Jesper Wallentin; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic vapour phase epitaxy; III-V semiconductor materials; nanowires; doping; solar cells; F:2013:Wallentin;

    Abstract : In this thesis, in situ doping during growth of III-V semiconductor nanowires, primarily for photovoltaic applications, is investigated. The nanowires were grown by metalorganic vapor phase epitaxy (MOVPE), with gold seed particles. READ MORE
