| 摘 要： | 本文从有限元伽辽金(Galerkin)方法出发,提出了计算任意势能变化半导体量子阱本征值的有限元方法,在该方法中,有限元仅用在量子阱区域,而半无限势垒的贡献用解析式给出,通过计算方量子阱及截短抛物线型势阱本征值证实了该方法的有效性。

| Abstract: | The finite—element method based on the Galerkin procedure is developed for analysing the cigenstates in quantum wells with arbitrary potential profiles. Finite elements are employed only within the well region, and the contribution of the semi—infinite barrier is evaluated analytically. The validity of the method is confirmed by applying the present method to a few canonical quantum-mechanical problems. |
