  1. 1. Synchrotron X-ray based characterization of technologically relevant III-V surfaces and nanostructures

    Author : Andrea Troian; NanoLund: Center for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; III-V semiconductors; high-k oxides; passivation; doping; XPS; AP-XPS; SPEM; XRF; full field X-ray diffraction microscopy; Fysicumarkivet A:2019:Troian;

    Abstract : Innovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) studied here.

  2. 2. Computational studies of core level XPS satellites in transition metal systems : Department of Quantum Chemistry, Uppsala University

    Author : Johnny Bustad; Högskolan i Gävle; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; adsorbates; shake-up; surface science; XPS; XES; INDO; model systems; Chemical physics; Kemisk fysik;

    Abstract : Upon core ionization of a free molecule or a molecule adsorbed on a metal surface, higher binding energy satellites are observed, so called "shake-up" satellites, which can be viewed as valence excitations simultaneously to the creation of the core hole. In this thesis, theoretical studies of such core level XPS satellites in transition metal systems are presented, as well as cluster calculations of XES spectra, using the quantum mechanical INDO method.

  5. 5. Value-adding deployment of corporate lean programs in multinational production companies

    Author : Sara Linderson; Monica Bellgran; Seyoum Eshetu Birkie; Lars Bengtsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lean production; Deployment; Program management; Company-specific production systems; XPS; Knowledge transfer; Strategy implementation; Lean produktion; Utrullning; Programledning; Kunskapsöverföring; XPS; Företagsspecifika produktionssystem; Strategiimplementering; Industriell ekonomi och organisation; Industrial Economics and Management;

    Abstract : Strategic improvement programs, which aim for corporate-wide lean transformation, are resource-demanding and challenging to deploy. Industrial manufacturers often develop company-specific production system (XPS) programs to coordinate the lean transformation simultaneously in multiple production sites. READ MORE
