Whereas its analysis appliance is restricted within the totally periodic structures such as super - lattice and quantum pots 但在此之前，对它的应用仅限于超晶格、量子点等完全规律性的材料。
To our great surprise , we saw that the resistance of the superlattice increased dramatically when we strengthened the magnetic field 结果大出意料之外，随著磁场的增强，我们看到超晶格的电阻急遽增加。
We immersed the system in a magnetic field , a procedure that enabled us to study dynamical processes involving the electrons in the superlattice 我们将系统放在磁场中，好研究超晶格里电子的动态过程。
The dependence of superlattice thermal conductivity on period length is investigated by nonequilibrium molecular dynamics simulation 摘要采用非平衡态分子动力学方法模拟了超晶格的法向导热系数随周期长度的变化关系。
This paper is mainly devoted to study of the quantum transport in semiconductor superlattice and phase transition of bec in optical lattice 本文主要对半导体超晶格中的bloch电子动力学以及光格子中玻色-爱因斯坦凝聚的相变问题进行研究。
The simulation results show that the two different materials building up the superlattice have a little affection on the thermal property to each other 模拟结果表明：不同粒子质量的两种材料组成的超晶格薄膜中，二者的导热性能相互间影响并不大。
Such behavior would be expected in a magnetic material but not in something like our superlattice , which was made entirely of nonmagnetic constituents 在磁性材料里，这种行为并不特别，但在我们的超晶格里则不然，因为它完全是由非磁性材料做成的。
However , the simulation results of the superlattice with 4 % lattice mismatch show that the thermal conductivity increases monotonically with the period length 而对于具有4 %晶格失配的超晶格模拟结果却表明，超晶格导热系数随周期长度的增大而单调上升。
