(PEEM), upon exposure to electromagnetic radiation (photons), secondary electrons are excited from the surface and imaged. PEEM was first developed in the early 1930s, using ultraviolet (UV) light to induce photoemission of (secondary) electrons. However, since then, this technique has made many advances, the most important of which was the pairing of PEEM with a synchrotron light source, providing tunable, linear polarized, left and right circularized radiation in the soft x-ray range. Such application
