Solid State Physics in a Nutshell: Topic 4-2: Powder Diffraction
About | Information | History | Online | Facts | Discovery
We begin this video by connecting the intensity to reciprocal space for polycrystalline materials using a concentric sphere model. We then show that one can measure this using omega two theta scans which radially grow a change in wave vector so it crosses different reflections. We also show that the distance between these spheres depends on the crystal system which gives rise to different intensity patterns.

Great videos! Just wanted to point out a small typo in this one -- around 1:30 you write out "tetrahedral" on the paper, though you are talking about tetragonal cells.
