  2. 1. Novel architectured, dislocation-free, III-Nitride structures for the next generation optoelectronic devices

    Author : Maryam Khalilian; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-Nitride materials; heteroepitaxy; 3D growth mode; optoelectronic devices; Fysicumarkivet A:2019:Khalilian;

    Abstract : III-Nitride (III-N) materials are promising building blocks of optoelectronic devices such as light emitting diode and laser diode due to the unique material properties. Furthermore, direct and tunable band gaps of III-N materials enable them to cover the entire visible-UV region of electromagnetic spectrum for device applications. READ MORE

  4. 2. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

    Author : Tobias Nyberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. READ MORE

  5. 3. Optical Modeling and Characterization of Layers and Multilayer Structures : Organic Optoelectronic Devices and Spectroscopic Ellipsometry

    Author : Leif A. A. Pettersson; Robert W. Collins; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This dissertation is on the subject of modeling and characterization of layers and multilayer structures with respect to their optical properties and characteristics. A number of different systems have been investigated; among them multilayer structures in the form of organic optoelectronic devices, anisotropic layers of conjugated polymers as well as inhomogeneous layers of porous silicon and oxidized silver.
