WitrynaGiven the essential role of the perovskite films in the device performance, it is of critical importance to develop reliable crystallization protocols to deposit high-quality perovskite layers via scalable methods. This review summarizes recent advances in emerging crystallization protocols for the large-scale deposition of perovskite thin films. WitrynaX-ray crystallography uses the principles of X-ray diffraction to analyze the sample, but it is done in many different directions so that the 3D structure can be built up. It is a technique that has helped to deduce the 3D crystal structure of many materials, especially biological materials. When you think of X-ray diffraction (XRD), a 2D ...

WitrynaCrystallographers can work out the atomic structure of almost anything. And they use this knowledge to answer why things behave the way they do. Crystallography reveals why diamonds are hard and shiny and why salt melts in the mouth. But the technique doesn’t just look at naturally-occurring crystals. Almost any material can be crystallised.
WitrynaPurification by recrystallization is an important tool for chemical synthesis and analysis.
