Development of an Ultrafast Low-Energy Electron Diffraction Setup

After studying ultrafast phase-change materials at the University of Technology in Sydney as well as the University of California Santa Barbara, Max Gulde returned to Germany. At the University of Göttingen, he received his diploma in physics in 2010 for the investigation of laser-triggered nano-emitters as potential sources for electron imaging and diffraction experiments. During this time, the idea of an ultrafast low-energy diffraction apparatus was born, ultimately leading to the development of ULEED. Today, Max Gulde uses ULEED together with molecular dynamics simulations to obtain insight into the non-equilibrium dynamics of molecularly thin, crystalline soft matter films.
