1. Transmission Electron Microscopy of 2D Materials : Structure and Surface Properties
Sammanfattning : During recent years, new types of materials have been discovered with unique properties. One family of such materials are two-dimensional materials, which include graphene and MXene. These materials are stronger, more flexible, and have higher conductivity than other materials. As such they are highly interesting for new applications, e. LÄS MER
2. Transmission Electron Microscopy of Semiconductor Nanowires
Sammanfattning : Semiconductor nanowires are studied by using transmission electron microscopy (TEM) based methods in this work. In the first section, the growth mechanism of gallium arsenide nanowires grown by chemical beam epitaxy is investigated. The nanowires are epitaxially grown from a gallium arsenide substrate by using gold seed particles as catalysts. LÄS MER
3. Multimodal and multiscale characterization of bone and bone interfaces in health and disease
Sammanfattning : Seeing is believing. Our understanding of phenomena often involves their direct observation. However, bone architecture is challenging to visualize given its multi-level hierarchical organization. LÄS MER
4. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films
Sammanfattning : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. LÄS MER
5. Transmission Electron Microscopy for Characterization of Structures, Interfaces and Magnetic Moments in Magnetic Thin Films and Multilayers
Sammanfattning : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). LÄS MER
