What is the difference between silicon wafer P111 and P100
If the crystal is body centered cubic lattice, the crystal orientation through the cube on the diagonal atoms
<111> is the coordinate of the direction vector<111> is expressed over the origin and point x = 1, y = 1, Z =1 on a straight line passing through the atom
Crystal growth direction<111><100><110>The coordinate system is set up in the crystal cell
