  1. 16. Electron Energy Loss Spectroscopy of III-Nitride Semiconductors

    Författare :Justinas Palisaitis; Per Persson; Lars Hultman; Jens Birch; Ernesto Coronel; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This Licentiate Thesis covers experimental and theoretical investigations of the bulk plasmon response to different compositions and strain states of group III-nitride materials. Investigated materials were grown using magnetron sputtering epitaxy and metal organic chemical vapour deposition and studied by Rutherford backscattering spectrometry, X-ray diffraction, electron microscopy and electron energy loss spectroscopy (EELS).

  3. 17. Valence Electron Energy Loss Spectroscopy of III-Nitride Semiconductors

    Författare :Justinas Pališaitis; Per Persson; Lars Hultman; Jens Birch; Vicki Keast; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This doctorate thesis covers both experimental and theoretical investigations of the optical responses of the group III-nitrides (AlN, GaN, InN) and their ternary alloys. The goal of this research has been to explore the usefulness of valence electron energy loss spectroscopy (VEELS) for materials characterization of group III-nitride semiconductors at the nanoscale.

  4. 18. Magnetron Sputter Epitaxy of Group III-Nitride Semiconductor Nanorods

    Författare :Alexandra Serban; Jens Birch; Ching-Lien Hsiao; Per Ola Åke Persson; Lars Hultman; Kimberly Thelander; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The III-nitride semiconductors family includes gallium nitride (GaN), aluminum nitride (AlN), indium nitride (InN), and related ternary and quaternary alloys. The research interest on this group of materials is sparked by the direct bandgaps, and excellent physical and chemical properties. LÄS MER

  7. 20. Tracing Smartphone-Enabled Customer Journeys : A Socio-Material Approach

    Författare :Patrik Stoopendahl; Jens Hultman; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Customer journey; Socio-material perspectives; Trace ethnography; Agency; Smartphone; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : This doctoral thesis delves into the transformation of the customer journey—that is, the direct and indirect interactions between a customer and retailer over time—in the smartphone era. Using a socio-material perspective, it goes beyond current visions of the customer journey, which often focus on emotions and experiences, and instead explores how agency is distributed across elements that include consumers and their relationship with their smartphone as a device and a gateway to a digital market infrastructure.
