21. YBCO nanowires to study nanoscale ordering in High-Tc Superconductors
Sammanfattning : We present the realization of YBa2Cu3O7-δ (YBCO) nanowires for both basic physics studies, which could help to elucidate the microscopic mechanisms of High critical Temperature Superconductors (HTS), and for novel applications.The first part of the thesis describes an improved nanopatterning procedure, based on e-beam lithography in combination with an amorphous carbon mask and a very gentle Ar+ ion etching.

22. Nanofabricated Devices Based on Molecular Motors: Biosensing, Computation and Detection
Sammanfattning : The thesis describes the use of molecular motors in nanofabricated devices designed for potential applications in biosensing, computation and detection. We utilize the well-established guiding principles for controlling the motion of actin filaments propelled by myosin molecular motors, and build upon these developments in order to improve upon previously demonstrated techniques, and establish new methods that, we believe, offer significant progress in these fields.

23. Lightguiding of Fluorescence in Nanowires : Principles, Optimization and Implementation for Biosensing
Sammanfattning : Due to their unique optical properties, III-V nanowires are promising candidates for the development of efficient solar cells, LEDs and nanoscaled lasers. The interaction of nanowires with fluorescent molecules is also of interest, as these nanostructures can act as nanoscaled optical fibers. LÄS MER
24. The Crystal Structure of III-V Semiconductor Nanowires: Growth and Characterization
Sammanfattning : This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. LÄS MER
25. Mechanosensing Using GaInP Nanowires
Sammanfattning : Mechanical forces exists in many cellular processes, including cell proliferation, migration, rearrangement and differentiation. The transformation of cancer cells from normal cells, cancer metastasis and cell rearrangement during morphogenesis all involve changes in cellular mechanical forces. LÄS MER
