  1. 36. Fabrication and characterisation of RGB LEDs based on nanowire technology

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Patrik Olausson; [2019]
    Keywords : RGB LEDs; InGaN; GaN; nitrides; platelets; nanotechnology; Technology and Engineering;

    Abstract : The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. READ MORE

  3. 37. Optimization of gas flow uniformity in enhancement of Metal Organic Chemical Vapor Deposition growth for III-nitrides

    University essay from Linköpings universitet/Halvledarmaterial

    Author : Kevin Olsson; [2019]
    Keywords : material science; mocvd; gan; semiconductors; gallium; nitride; fluid dynamics; termoelements; thermocouple; injector; heat transfer; thermal distribution; graphite; HEMT; III-nitrides; hot-wall MOCVD system; GaN-on-SiC; gas flow profile; laminar flow;

    Abstract : The thesis focuses on the gas flow profile optimization of a non-conventional injector in a hot-wall MOCVD system. The injector’s gas flow profile is simulated with CFD and demonstrates awell-behaved laminar flow with a parabolic profile. READ MORE

  4. 38. Balancing use and conservation in marine spatial planning - Perspectives of sustainability and the ecosystem approach in a Swedish context

    University essay from Göteborgs universitet / Institutionen för ekonomi och samhälle

    Author : Julia Sandberg; [2018-03-13]
    Keywords : marine spatial planning; the Ecosystem Approach; sustainable development;

    Abstract : The environmental concern and interest in marine resources are growing, which is reflected within marine policies in the European Union. In 2007 the Integrated Maritime Policy (IMP) was adopted, aiming at collecting and integrating marine policies in one framework. READ MORE

  5. 39. Using Blue Mussels as a Tool for Mitigating Eutrophication in the Baltic Sea

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Johanna Ståhle; Linnea Henriksson; [2018]
    Keywords : Life cycle analysis LCA ; recycling of nutrients; blue mussels; mussel farm; mussel meal; biogas; compost;

    Abstract : Eutrophication is a consequence of excess nutrients in the water which leads to increased algaegrowth, reduced water transparency and hypoxic bottoms. This is the biggest environmental problemfor the Baltic Sea which recently has resulted in stricter legislations and other initiatives to help theBaltic Sea to recover. READ MORE

  6. 40. Selective Area Growth of AlGaN pyramid with GaN Multiple Quantum Wells

    University essay from Linköpings universitet/Halvledarmaterial

    Author : Hsin-Yu Chen; [2018]
    Keywords : selective area growth; MOCVD; AlGaN pyramid; GaN multiple quantum wells; undesired deposition;

    Abstract :   Since Shuji Nakamura, Hiroshi Amano, and Isamu Akasaki won the 2014 Nobel prize in Physics owing to theircontributions on the invention of efficient blue GaN light emitting diodes, GaN became an even more appealingmaterial system in the research field of optoelectronics. On the other hand, quantum structures or low-dimensionalstructures with properties derived from quantum physics demonstrate superior and unique electrical and opticalproperties, providing a significant potential on novel optoelectronic applications based on the employment of quantumconfinement.
