The work presented in this manuscript focuses on the structural (size, strain, defects, composition) investigation of Ge nano-islands grown on both nominal and pre-patterned Si(001) substrates by Molecular Beam Epitaxy, using grazing incidence (anomalous) X-ray diffraction and scattering at the European Synchrotron Radiation Facility (ESRF). The samples were either prepared in independent MBE chambers and then characterized ex situ on the ID01 ESRF beamline, or they were characterized in situ during their MBE growth, using the BM32 ESRF beamline setup. The dynamical scattering effects occurring in grazing incidence have been studied on the basis of finite element simulations of the strain fields in nano-islands, revealing the strong influen...
