Nanotechnologies rely on the introduction of strain engineering to enhance semiconductor devices performances. As a consequence, non-invasive characterization methods with high spatial resolution and strain sensitivity on low-amount-of-matter samples are required. This PhD work focuses on methodology of X-ray diffraction techniques performed in the Bragg geometry, which allows probing the structural properties of crystalline samples. Firstly, the Scanning X-ray Diffraction Microscopy technique, developed on a fast-timescale at the ESRF ID01 undulator beamline, is described through a thorough analysis of an experiment performed on ultra-thin strained SiGe-on-insulator patterns. Secondly, this manuscript focuses on two coherent diffraction im...
