Energy levels are calculated for three-dimensional (3D) quantum-confinement structures with finite potential barriers. GaAs/Ga0.63AI0.37As, Ga0.47In0.53As/InP and Ga0.47In0.53As/AI0.48In0.52As systems are considered. Analytic results are presented for spherical structures including the effects of nonparabolicity. A numerical method is also presented for the calculation of the energy levels in a 3D quantum-confinement structure in the shape of a cube or a parallelopiped. The method is applied for calculating the energy shift in a cylindrical dot of the GaAs/Ga0.63AI0.37As system.
