1. The Cu(111) surface studied by scanning tunnelling microscopy and spectroscopy
Sammanfattning : .... LÄS MER
2. Scanning Tunnelling Microscopy Studies of Na Islands on Graphite, Impurity Interactions on Cu(111) and Low Temperature Structures of S/Cu(111)
Sammanfattning : A scanning tunnelling microscope (STM) can reveal the atomic order of a surface as well as details of its electronic structure. In the present work STM, in combination with core and valence photo-electron spectroscopy and low energy electron diffraction (LEED) was applied to three different systems: (i) simple metal quantum wells in the form of Na films and islands on highly oriented pyrolytic graphite (HOPG), (ii) low temperature S/Cu(111) structures discovered in the course of this work and (iii) impurities on Cu(111).

3. Synchrotron Radiation Studies of Molecular Building Blocks for Functional Materials
Sammanfattning : The research on new materials is a primary driving force for progress in human society. One of the most significant research topic nowadays is the development of new functional materials for technological applications, like perovskite implemented in solar cells, and graphene as a representative for the new 2D materials family.

4. Bound by long-range interactions: Molecular crystals and benzene on Cu(111)
Sammanfattning : This thesis investigates molecular systems bound by long-range interactions. Westudy molecular crystals held together by van der Waals forces and the physisorption of benzene (Bz) on Cu(111). LÄS MER
5. Metal accumulation by plants : evaluation of the use of plants in stormwater treatment
Sammanfattning : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. LÄS MER
