How are crystallographic planes specified
WebLecture Crystallography - University of Notre Dame Web22 de set. de 2016 · These are operations that take the crystal structure back to itself. In your cubic example, you can rotate 90 degrees about the z-axis, taking x -> y and y->-x, but the structure does not change. Thus, [100] and [010] are equivalent (and, similarly, so is [001]). – Jon Custer Sep 22, 2016 at 17:54 Add a comment 1 Answer Sorted by: 5
