1. 21. Electrical Properties of planar Metal-GdN-Metal junctions for Spintronic Applications

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Felicia Ullstad; [2015]
   Keywords : nitride; gadolinium; spintronic; rare earth nitride; ferromagnetism; ferromagnetic; Semiconductor; Physics and Astronomy;

   Abstract : In this thesis the properties of planar metal-gadolinium nitride-metal junctions have been studied with the aim of establishing ohmic and Schottky contacts to thin polycrystalline films of n-type gadolinium nitride (GdN). GdN is an intrinsic ferromagnetic semiconductor of the rare earth nitride series. READ MORE

3. 22. Setup and control of a test reactor for catalysis with optical access

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : Christoffer Pichler; [2014]
   Keywords : Physics; Catalysis; Laser Induced Fluorescence; Mass spectrometer; Physics and Astronomy;

   Abstract : CO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. READ MORE

4. 23. Production of Anthracene (C14H10) Clusters using Cold Aerodynamic Source (CAS) and Verification of the Products via Time of Flight Spectroscopy

   University essay from Lunds universitet/Fysiska institutionen

   Author : Saloan Algharbi; [2013]
   Keywords : - Clusters source Cold Aerodynamic Source CAS . - Anthracene C14H10 . - Time of Flight Spectroscopy.; Physics and Astronomy;

   Abstract : Molecular cluster is a nanoparticle that is defined as an agglomerate of few up to 106-7 of molecules (corresponding to 1- 100 nm in size) that can be manipulated by the cluster beams. Molecular cluster properties typically lie between the individual molecule and bulk matter properties. READ MORE

5. 24. Studies of Au Clusters on a Graphene Covered Ir(111) substrate: Cluster Growth and CO Adsorption

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Johan Knutsson; [2012]
   Keywords : Au; Clusters; Graphene; XPS; LEED; CO; Catalysis; Activity; Physics and Astronomy;

   Abstract : The chemical properties of 0.2-1 ML Au clusters have been studied using X-ray photoelectron spectroscopy (XPS). By exposing the clusters to CO, at 10^-7 mbar, in periods of two minutes, while systematically increasing the cluster size, a correlation between cluster size and CO adsorption was found. READ MORE

6. 25. The HPXPS Instrument at MAX-lab : a Powerful Tool for In Situ Catalysis Investigations

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Niclas Johansson; [2012]
   Keywords : XPS; LEED; HPXPS; trilayer; FeO; Physics and Astronomy;

   Abstract : A new instrument for near ambient x-ray photoelectron spectroscopy investigations of surfaces has been installed at beamline I511 of the MAX-II electron storage ring at the MAX IV Laboratory. This high pressure x-ray photoelectron spectroscopy instrument is capable of surface chemistry investigations in near ambient pressures using x-ray photoelectron spectroscopy (XPS), a technique that traditionally is limited to ultrahigh vacuum.
