玻恩-卡门边界条件
Born-von Kamen boundary condition
玻恩一卡门边界条件Born一von Kamen boundarycondition在求解晶体中电子系统等问题时，为避免表面效应而选取的一种人为的边界条件。又称周期性边界条件。 在求解晶体中电子的薛定谬方程时，采用某种边界条件来表示电子限制在晶体体积V之内。若不考虑表面效应，或仅限于研究不受表面影响的体材料中的问题，可以只根据数学上的方便来选取边界条件。事实上，只要晶体体积和尺度足够大，可以预期体材料结果不会受表面影响，于是可以选材料为立方体，边长L一Vl，3o设想立方体的每个表面都与它的对立面相接，那么，到达表面的电子将不被反射回来，而是离开材料，并且同时在对立面的相应点重新进入材料。于是，可以写出 必(x，y，之+L)~沪(x，夕，之) 必(x，y千L，之)一必(x，y，动 动(x+L，y，之)=沪(x，y，之)这就是玻恩一卡门边界条件。 (王以铭、曾令之)
