摘要
讨论了无限深和有限深量子阱电子系统的维数.在无限深量子阱中,随着阱宽由大减小到零,量子阱的维数由3单调减小到2;有限深量子阱中,在阱宽较大或阱宽趋于零时,量子阱电子系统的维数都趋近于3,随着阱宽的减小,量子阱的维数呈现出先减小后增大的情况,存在一个维数极小值.
The dimension for infinite potential and finite potential quantum well is discussed. The dimension of infinite potential well monotonically decreases from 3 to 2 with the decrease of well width. In finite potential well, the dimension of quantum well tends to 3 when the well width is larger or goes to zero. As the well width decreases, the dimensions of the quantum well decreases firstly and then increase, and have their minima.
