摘要 根据密度泛函理论,用自洽迭代的方法求解二雏方形量子点中有杂质时电子(N=1-12)的薛定谔方程,对绝对零度情况下处于基态电子的总能量进行了数值计算,并讨论了杂质对量子点中电子基态能量的影响,得出了方形量子点中多电子系统基态的一些性质. Using density-functional theory, the Schr6dinger equation of a 2D square quantum dot with impurity has been solved self-consistently. The ground state energy has been computed at zero temperature. We also discuss the influence of impurities on the ground energy of the square quantum dot.
