11. Plasmonic Nanostructures for Molecular Spectroscopy
Sammanfattning : This thesis focuses on the fabrication, characterization and utilization of nanostructures for chemical sensing and optical enhancement processes.Noble metal nanostructures can support localized surface plasmon resonances (LSPRs), which amplify the strength of the electromagnetic field close to the structures.

12. ON THE COUPLING OF THE LOCALIZED PLASMON AND INTERBAND TRANSITIONS IN NICKEL NANOANTENNAS
Sammanfattning : Interaction of light with metallic nanostructures smaller than the wavelength leads to excitation of collective oscillations of “free” conduction electrons. This effect leads to locally enhanced electric fields inside and outside the nanoparticle and is called localized surface plasmon resonance (LSPR). LÄS MER
13. Reflective structural colors and their actuation using electroactive conducting polymers
Sammanfattning : The integration of inorganic photonic nanostructures with organic materials opens new possibilities to dynamically modify the optical response of photonic devices. This thesis focuses on how to generate efficient reflective structural colors and tune them in combination with a conducting polymer (CP). LÄS MER
14. Nanoplasmonic Enhancement of Photon-to-Electron Conversion in Functionalized Iron Oxide Photoanodes
Sammanfattning : The ever increasing energy demand of modern society clashes with the accelerating depletion of the fossil fuels from which most of this energy is taken today. Moreover, fossil fuels consumption poses a severe threat on the Earth’s environment and climate through global warming. LÄS MER
15. Nanostructured Model Electrodes for Studies of Fuel Cell Reactions
Sammanfattning : There is currently a general need for alternative and sustainable energy systems. As part of such a system, the polymer electrolyte fuel cell (PEMFC) offers efficient and emission free energy conversion. LÄS MER
