Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Diffraction theory describes how wave fields—acoustic, electromagnetic or quantum—interact with obstacles and apertures, producing characteristic patterns of scattering and interference. At its heart ...

Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...
