Free-electron laser (FEL) sources can generate tunable short-wavelength coherent pulses that can be used for studying structure and dynamics of matter in different forms. In this open collection, we ...
What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs) are a revolutionary type of X-ray source that produce ultra-short, highly intense pulses of X-rays. Unlike conventional X-ray ...
At the nanoscale, where device dimensions approach the electron's mean free path, the scattering events that typically hinder electron motion in bulk materials can be substantially reduced. In an ...
