Nanoscale X-ray holographic imaging

Description of Activities:

We use coherent X-ray light sources to image quantum materials on the nanometer length scale. By exploiting the resonances of the constituent atoms in the soft X-ray region, we can explore how element specific defects and strain dictate the properties of these materials. One of the challenges in operating in this regime is that X-ray lens are difficult to manufacture. To overcome this limitation we exploit a lens-less imaging technique in which we replace the lens with numerical techniques to convert measured diffraction patterns into real space images. We work towards improving this technique so that we can capture dynamics in these materials on the nanoscale.
