Application of the potential energy of crystal face Computing with Matlab

The property of the crystal lattice structure is one of the important content of solid physics teaching.The potential energy of crystal lattice becomes the subject of intense research.That can be used study movement of the electronic in crystal lattice.The potential energy in crystal lattice is calculated by principle of superposition of electric potential.But the potentials of many electrons are hard to lay hold of.In this paper we develop some methods of show the potential in pictures.We provide methods that will help students understand and apply the property of the crystal lattice.
