1. Spectra and Dynamics of Excitations in Long-Range Correlated Structures
Abstract : Vad karaktäriserar en kristall? Svaret på denna till synes enkla fråga blir kanske att det är en anordning av atomer uppradade i periodiska mönster. Så ordnade strukturer kan studeras genom att det uppträder så kallade Braggtoppar i röntgendiffraktionsmönstret. READ MORE

2. Confinement and resonant phenomena in small Bi2Sr2CaCu2O8 mesa structures
Abstract : In this thesis, intrinsic Josephson junctions, naturally formed in the stronglyanisotropic high-temperature superconductor Bi2Sr2CaCu2O8, are studied experimentally.Small mesa structures are fabricated on the surface of singlecrystals using micro- and nano-fabrication tools, focused ion beam is used toreduce the mesa-area to ≈ 1 × 1 μm2.

3. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation
Abstract : 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. READ MORE
