中文摘要	the dependence of the electronic energy levels on the size of quantum dots (qds) with the shape of spherical lens is studied by using the b-spline technique for the first time. within the framework of the effective-mass theory, the values of electronic energy levels are obtained as a function of the height, radius and volume of qds, respectively. when the height or radius of qds increases, all the electronic energy levels lower, and the separations between the energy levels decrease. for lens-shape qds, height is the key factor in dominating the energy levels comparing with the effect of radius, especially in dominating the ground-state level. these computational results are compared with that of other theoretical calculation ways. the b-spline technique is proved to be an effective way in calculating the electronic structure in qds with the shape of spherical lens.
