6. X-Ray Photoemission Spectroscopy Characterization of Fe(II)- and Fe(III)-Phthalocyanine Molecular Films
University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysikAbstract : This thesis investigates the electronic structure of iron phthalocyanine (Fe(II)Pc) andiron phthalocyanine chloride (Fe(III)PcCl) immobilized on surfaces. For this purposetwo different deposition methods are used and compared: smearing the molecularpowder under atmosphere condition and evaporation of a molecular layer inultra-high vacuum. READ MORE

7. Photoemission electron microscopy of localized surface plasmons in silver nanostructures: Experiments and simulations
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikAbstract : In this work, spatially resolved localized surface plasmons (LSPs) in individual silver nanocubes and nanoellipsoids are imaged with a photoemission electron microscope (PEEM). Using broadband laser pulses with photon energies below the work function threshold of the material, multiphoton photoemission (MPPE) processes coupled to the LSPs governs the strong enhancement of the plasmonic near-field detected in the PEEM.

8. Surface Studies on Industrial Aluminium Alloys
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikAbstract : Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. READ MORE

9. Numerical simulation of Rosetta Langmuir Probe
University essay from Rymd- och plasmafysikAbstract : By modelling and simulating the ESA spacecraft Rosetta in a plasma with solar wind parameters, and simultaneously simulating a particle detection experiment of Langmuir probe voltage sweep type using the ESA open source software SPIS Science, we investigate the features of Rosetta’s envi- ronment in the solar wind and the e↵ect of photoemission from the space- craft on the measurements made by the Langmuir Probe instrument on board Rosetta. For a 10 V positively charged spacecraft and Maxwellian distributed photoelectron emission with photoelectron temperature, Tf = 2 eV in a plasma of typical 1 AU solar wind parameters: ne = 5 ⇥ 106 m3, vSW = 4 ⇥ 105 m/s, Te = 12 eV, Tion = 5 eV, we detect a floating potential of 6.
