Cover Story: Imaging the three-dimensional morphology of large surface areas (tens of microns) at a resolution that allows us to understand the surface quality and its modification is challenging. As a proof of principle, PET films were characterized to demonstrate the capabilities of ptychography using X-ray free-electron lasers, currently developed at FLASH at DESY (Hamburg, Germany), to image macroscopic samples. In combination with scanning electron microscopy and complemented by surface chemistry studies using X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy, this new technique was used to study the effects of two different plasma treatments on the surfaces of PET films. View this paper
