I sent you a PM several days ago. Did you get it? Anyway, orthorhombic is not very different from cubic. Compare these two and you will find the answer.

In Wurtzite crystal structure, this three-digit notation is not used. Instead, four-digit notation is used for the hexagonal unit cell with coordinated a1, a2, a3, and c. For example, the stacking direction is (0001) and the side face belongs to the family of {1-100} planes.

Thanks a lot for the clear image. It helps a lot.

I am reading some theoretical papers on the defects in semiconductors. Theorists can calculate the formation energy of a certain kind of defect. If the number is too big, this defect is very unlikely to be seen. So what does this “formation energy” mean? Is that the energy necessary to move...
