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

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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. LÄS MER

  3. 2. Waste heat recovery system with new thermoelectric materials

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Fredrik Borgström; Jonas Coyet; [2015]
    Nyckelord :;

    Sammanfattning : Increasing fuel prices, higher demands on "greener" transports and tougher international emission regulations puts requirements on companies in the automotive industry in improving their vehicle fuel efficiency. On a typical heavy duty Scania truck around 30% of the total fuel energy is wasted through the exhaust system in terms of heat dissipated to the environment. LÄS MER

  4. 3. Identification of process induced defects affecting the performance of nanowire based solar cells by spatially resolved photocurrent measurements

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik

    Författare :Calvin Kan; [2013]
    Nyckelord :Nanowires; solar cells; nanotechnology; sustainable development; photocurrent measurements; energy; Technology and Engineering;

    Sammanfattning : Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. LÄS MER

  5. 4. Energy Efficiency - Can Nanotechnology Change the Equation?

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fredrik Andrén-Sandberg; [2011]
    Nyckelord :energy efficiency nanotechnology; Technology and Engineering;

    Sammanfattning : How can nanoscience be used to raise the energy efficiency of established industrial technologies and in residential housing By reviewing the literature concerning nanotechnology and the impact it may have on energy efficiency, it becomes quite clear that it will have a mayor impact in the future. Much of the impact will probably come in the form of enabling technologies that could be used to improve existing technologies that are already present today, such as heat-coatings for turbine blades or non sticking surfaces for boilers.
