摘要

研究处于N 个有限深对称势阱中的电子态. 从薛定谔方程出发,在N = 1、2、3 和4 的情况下,用Mathematica 数值求解由标准条件决定的线性方程组,精确计算出电子的能级和波函数.直观地展示电子能级分裂成能带的机理.

Abstract

The electronic states in the symmetric N - potential wells are studied. Based on the Schrdinger equation,the linear equations determined by the standard conditions in the case of N = 1,2,3 and 4 are solved,the energy level and wave function are accurately calculated by using Mathematica. The mechanism of the energy level splitting into energy band is exhibited.
