  3. 2. Growth of ZnO/GaN distributed Bragg reflectors by plasma-assisted molecular beam epitaxy

    Författare :David Adolph; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Oxides; GaN; distributed Bragg reflector; MBE; molecular beam epitaxy; ZnO; Nitrides; DBR;

    Sammanfattning : This thesis describes epitaxial growth of ZnO/GaN distributed Bragg reflectors by hybrid plasma-assisted molecular beam epitaxy on GaN(0001). The unique hybrid approach employed the same growth chamber for continuous growth of both ZnO and GaN without exposing the layers to the ambient conditions. LÄS MER

  4. 3. Technology for biocomputational devices based on molecular motors

    Författare :Frida Lindberg; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular motors; Nanofabrication; Biocomputation; Nanostructures; Fysicumarkivet A:2019:Lindberg;

    Sammanfattning : For many multivariable problems there are no efficient algorithms for finding solutions. To this day, conventional electronic computers mainly solve problems in a sequential manner. This sequential operation prevents problem-solving within a reasonable time-frame due to superpolynomial, and sometimes even exponential, time complexities. LÄS MER

  5. 4. Molecular Beam Studies of Interactions Between Ice Surfaces and Atmospherically Relevant Molecules

    Författare :Liza Romero Lejonthun; Göteborgs universitet; []

    Sammanfattning : The discovery of the ozone hole over Antarctica in 1985 was one of the environmental issues that attracted most attention worldwide in the end of the last century. The cause of the ozone hole formation was proven to be coupled to the emission of chlorofluorocarbons (CFCs). LÄS MER
