1. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices
Sammanfattning : 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. LÄS MER
2. Novel architectured, dislocation-free, III-Nitride structures for the next generation optoelectronic devices
Sammanfattning : 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. LÄS MER
3. Junction Engineering in Nanostructured Optoelectronic Devices
Sammanfattning : Semiconductor nanowires have proven to be promising building blocks for next-generation optoelectronic devices. The nanometric dimensions of nanowires provides strain relaxation capability, thus enabling the heteroepitaxy of III-V materials on silicon, as well as providing the possibility of realizing optoelectronic devices with lattice-mismatched material combinations.
