  3. 2. Atom-Probe Field-Ion Microscopy of Electronic Materials

    Författare :Qiu-Hong Hu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Au GaAs; ohmic contact; superconductors; oxygen ordering; AuGe GaAs; defects; Ag GaAs; Schottky contact; YBa2Cu3O6 delta; APFIM;

    Sammanfattning : This thesis presents work in which atom-probe field-ion microscopy (APFIM) has been applied to two types of electronic materials. In the case of metal/GaAs contacts, the purpose was to characterise the microstructure of the contact interface, particularly the chemical composition variation across the interface. LÄS MER

  4. 3. Atom Probe Field Ion Microscopy of Surface Zones, Coatings and Interfaces

    Författare :Anders Kvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ag GaAs; ohmiccontact; Au GaAs; Schottky contact; Cu3Au; APFIM; AuGe GaAs; gradient sintering; cemented carbides; CVD;

    Sammanfattning : This thesis is focused on developingmethods for high resolution microanalysis of coatings on a substrate, andsurface zones of a bulk sample using atom probe field ion microscopy,APFIM. The APFIM technique is described and some examples of its applications to semiconductors,cemented carbides and intermetallic compounds are given. LÄS MER

  7. 5. Modalities of Place: On Polarisation and Exclusion in Concepts of Place and in Site-Specific Art

    Författare :Gunnar Sandin; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :HUMANIORA; HUMANITIES; interior design; Architecture; Actants; Modalities; Place; Site-Specific Art; Arkitektur; inredningsarkitektur;

    Sammanfattning : In this thesis the notion of place is studied by way of investigating the “non-place” which is excluded or opposed, whenever a place is defined. “Non-place” is used here as a meta-concept, covering various recurring types of opposition to “place,” and it therefore represents a profoundly incoherent spect-rum of realities and concepts.
