1. Thermodynamic Investigation of Co-Cr Alloys
Sammanfattning : In a collaborative effort between the Divison of Metallurgyand the Divison of Computational Thermodynamics, RoyalInstitute of Technology (KTH), Stockholm, Sweden, experimentalinvestigations have been carried out in the binary Co-Crsystem. The experimental strategy has been to measure thethermodynamic activities of Cr by the solid oxide electrolytegalvanic cell technique, as well as to measure the molar heatcapacities of the alloys, as function of temperature, by theDSC technique.

2. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon
Sammanfattning : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. LÄS MER
3. Scanning Tunneling Microscopy Induced Luminescence Studies of Semiconductor Nanostructures
Sammanfattning : This thesis treats scanning tunneling luminescence (STL) investigations of semiconductor nanostructures. The STL technique combines scanning tunneling microscopy (STM) with detection of photons, induced by the tunneling electrons. The high spatial resolution in STM and the local excitation allow for optical investigations on the nanometer-scale. LÄS MER

5. Calibration Procedure and Industrial Applications of Coherence Scanning Interferometer
Sammanfattning : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. Measurement and characterization of the areal nature of the surface allows the manufacturer to alter how the surface interacts with surroundings. LÄS MER
