Crystal structure of Silicon - Physics Stack Exchange
网页2014年11月14日 · For the green atom the V lies in the plane of the screen. In effect you get the red atom by rotating the green atom 90º about a vertical axis. So even the primitive cell contains two silicon atoms, and the compound FCC cell contains four primitive cells. Despite this, every silicon atom is indeed at the centre of a tetrahedron.
