We coupled an in-situ transmission X-ray microscope (TXM) with a Nd:YAG pulsed laser with a 532-nm wavelength and a 6-ns pulse width. This system was employed to investigate the photo-induced morphological evolution in Au thin films during shot-by-sh

We report a quantitative full field electron density mapping of nano-scale objects by coherent x-ray diffractive imaging (CXDI). The projected electron density maps of two specimens, a single AuNi nanocrystal and a cluster of multi Au nanocrystals, w

A quantitative height profile image of a silicon nano-trench structure was obtained via coherent diffraction imaging (CDI) utilizing focused X-rays at a photon energy of 5.5 keV. The ability to optimize the spatial coherence and the photon flux densi
