Planes and directions in the silicon lattice
Silicon is diamond cubic. These are the two orientations nearly every wafer is cut on — the same cell, sliced two different ways. Drag either one to turn it.
Tutorials
Each one ends with worked examples you can step through. Start at the top if indices are new to you.
Reference
For structures rather than indices, the companion Lattice Models viewer holds 33 crystal structures in 3D.
Build a set
This set
A first-try answer with no reveal scores 1. Correct on a later try scores ½. After a reveal the question scores 0 but still tells you whether you had it right.
Running totals

Pick your topics and materials, then New set of 4. Every set is generated fresh, so you will not see the same four questions twice.
Explore
Type any index and watch the plane or direction appear. Nothing here is scored.
