  1. 1. Optics and Instrumentation for Compact Soft X-Ray Microscopy

    Författare :Göran Johansson; KTH; []
    Nyckelord :x-ray; multilayer; optics; microscopy;

    Sammanfattning : This thesis describes thedevelopment of soft x-ray reflective optics and instrumentationfor compact soft x-ray microscopy. This microscope operates atthe wavelength 3.374 nm in the water-window (2.3 - 4. LÄS MER

  3. 2. Laboratory soft x-ray microscopy and tomography

    Författare :Michael Bertilson; Hans Hertz; Gerd Schneider; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; Diffractive optics; Zone plates; X-ray microscopy; Soft X-ray physics; Tomography; Optics; Optik; Physics; Fysik;

    Sammanfattning : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. LÄS MER

  4. 3. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation

    Författare :Per Takman; Hans Hertz; Janos Kirz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soft x-ray microscopy; water window; compact; laser plasma; liquid jet; zone plate optics; Physics; Fysik;

    Sammanfattning : This thesis describes the development of a sub-60-nm full-period resolution compact soft x-ray microscope operating in the water-window region (2.3-4.4 nm). Soft x-ray water-window microscopy is a powerful technique for high-resolution imaging of organic materials exploiting the natural contrast mechanism between carbon and oxygen, cf. LÄS MER

  5. 4. Soft X-ray Multilayer Mirrors

    Författare :Fredrik Eriksson; David Windt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is focused on the design, growth and characterization of soft x-ray multilayer mirrors with the emphasis on the wavelength region called the water window (λ=2.4-4.4 nm). LÄS MER

  7. 5. Optical Characterization and Optimization of Display Components : Some Applications to Liquid-Crystal-Based and Electrochromics-Based Devices

    Författare :Iryna Valyukh; Claes-Göran Granqvist; Ewa Wäckelgård; Hans Arwin; Ola Hundery; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ellipsometry; liquid crystal; LCD; optical anizotropy; electrochromic; inverse problems; Optics; Optik; Optical physics; Optisk fysik; Numerical analysis; Numerisk analys; Solid State Physics; fasta tillståndets fysik; Information Systems; data- och systemvetenskap;

    Sammanfattning : This dissertation is focused on theoretical and experimental studies of optical properties of materials and multilayer structures composing liquid crystal displays (LCDs) and electrochromic (EC) devices. By applying spectroscopic ellipsometry, we have determined the optical constants of thin films of electrochromic tungsten oxide (WOx) and nickel oxide (NiOy), the films’ thickness and roughness.
