Reflection-mode ptychography CDI is used with high harmonic generation illumination to image copper nanostructures buried beneath 100nm of aluminum. A modified version of ptychography CDI is utilized to obtain absolute reflectivity images, allowing non-destructive detection of diffusion and oxidation at the Al-Cu and Al-SiO2 boundaries, confirmed by Auger Electron Spectroscopy.
