Třírozměrná elektronová difrakce v nanokrystalografii
3D Electron diffraction: a quantum leap forward in nanocrystallography
Determination of atomic structure of crystalline solids, i.e. structural crystallography, is a key analytical technique in most of solid-state science fields. The standard approach to the crystal structure determination is the analysis of diffraction of suitable radiation, typically x-rays, on the crystal. X-rays, however, require a rather large crystals, typically >10 micrometers. Recently, a tremendous progress could be made towards the analysis of much smaller crystals by using electrons as the probing radiation. Although only about 15 years old, the technique of so called 3D electron diffraction has already significantly changed the science of crystallography. It allowed problems resisting solution for decades to be solved in days or weeks, and allowed obtaining results unavailable by any other method. The lecture will highlight some of these achievements, but it will also give account on problems and challenges that this young method still faces.
