Coherent X-ray diffraction imaging of photo-induced structural changes in BiFeO₃ nanocrystals

, 2016
Multiferroic materials that exhibit coupling between ferroelectric and magnetic properties are of considerable utility for technological applications and are also interesting from a fundamental standpoint.

High-resolution ab initio three-dimensional X-ray diffraction microscopy

, 2005
Coherent X-ray diffraction microscopy is a method of imaging non-periodic isolated objects at resolutions only limited, in principle, by the largest scattering angles recorded.

Untersuchung von Magnetostriktiven und Piezotronischen Mikrostrukturen und Materialien für biomagnetische Sensoren mittels Röntgenstrahlen [PDF]

, 2021
Detecting electric potential differences from the human physiology is an established technique in medical diagnosis, e.g., as electrocardiogram. It arises from a changing electrical polarization of living cells.

High-resolution and high-sensitivity phase-contrast imaging by focused hard x-ray ptychography with a spatial filter [PDF]

We demonstrate high-resolution and high-sensitivity x-ray phase-contrast imaging of a weakly scattering extended object by scanning coherent diffractive imaging, i.e., ptychography, using a focused x-ray beam with a spatial filter.

Real-space imaging of polar and elastic nano-textures in thin films via inversion of diffraction data

, 2022
Exploiting the emerging nanoscale periodicities in epitaxial, single-crystal thin films is an exciting direction in quantum materials science: confinement and periodic distortions induce novel properties.

Multiscale X-ray tomography for shale microstructure and mechanical behaviour [PDF]

Studying shales and other sedimentary rock systems is important to provide a fundamental understanding of their microstructural properties, including the mechanical response and the permeability of liquids and gases. Understanding the pore scale physical

High-resolution X-ray ptychography for magnetic imaging [PDF]

, 2018
The resolution in standard X-ray microscopes is limited by the focusing element, e.g. Fresnel Zone Plates (FZP), and stays in the range of 20 nm for highly efficient plates.

Nanofocusing Refractive X-Ray Lenses [PDF]

, 2010
This thesis is concerned with the optimization and development of the production of nanofocusing refractive x-ray lenses. These optics made of either silicon or diamond are well-suited for high resolution x-ray microscopy.
