With the breakthrough of the molecular beam epitaxy (MBE) and metal organic chemical vapor deposition (MOCVD) and various etching technology, researchers have been able to fabricate miscellaneous superlattice quantum well materials.
As superlattice quantum well materials can achieve the quantum size effect, also can realize the control of the semiconductor energy band and physical properties by changing the ratio of materials, the width of potential well or potential barrier [1-3].
