  2. 21. Resonant and Non-Resonant Electron Spectroscopy of Free Molecules and Free Clusters

    Author : Raimund Feifel; Michael Meyer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Resonant electron spectroscopy has been performed on the diatomic molecules CO, N2 and HCl. Core-excitations were made to bound and dissociative intermediate electronic states. Fundamental interference phenomena are observed and discussed in the framework of ”X-ray Raman Scattering Theory”. READ MORE

  4. 22. Microstructure and Thermal Degradation of PVC with Improved Thermal Stability

    Author : Mikael Rogestedt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Although the low thermal stability of poly(vinyl chloride) (PVC) has been an area of intensive research, the relation between microstructure and degradation behaviour is still not fully understood. This thesis deals with the structure, thermal degradation and modification of ordinary PVC. READ MORE

  5. 23. Fabrication, Characterization and Applications of Porous Silicon Thin Films and Multilayered Systems

    Author : Shahin Zangooie; John A. Woollam; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Variable angle spectroscopic ellipsometry was used for characterization of single- as well as multilayered systems of porous silicon. In addition to the complex structures such as Bragg reflectors and Fabry-Pérot filters, more advanced continuos porosity profiles were manufactured in a controlled manner. READ MORE

  6. 24. Nuclear Dynamics in Linear and Non-linear X-ray Processes

    Author : Quan Miao; Faris Gel'mukhanov; Vincenzo Carravetta; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : New generations of brilliant synchrotron radiation sources and intense X-ray and optical lasers have opened unprecedent opportunities in linear and non-linear spectroscopies of molecules. This together with new instrumentation calls for further development of theory to explain observations and suggest new experiments. READ MORE

  7. 25. Precursors and defect control for halogenated CVD of thick SiC epitaxial layers

    Author : Milan Yazdanfar; Erik Janzén; Olle Kordina; Henrik Pedersen; Stephen Saddow; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Silicon carbide (SiC) is a very hard semiconductor material with wide band gap, high breakdown electric field strength, high thermal conductivity and high saturation electron drift velocity making it a promising material for high frequency and high power devices. The performance of electrical devices is strongly dependent on the quality, doping level and thickness of the grown epitaxial layers. READ MORE
