摘　　要：采用最佳微扰的方法,对强磁场中无机半导体/有机低维复合结构中束缚态的跃迁能量在理论上进行了计算.结果表明,在强耦合条件下,这种束缚态的基态与低激发态的跃迁能量是耦合常数和磁场强度的函数,跃迁能量随耦合常数的增加而增大,磁场强度不同时跃迁能量也发生变化,并且质量比σ=me/mh对跃迁能量也有影响.　The bound states of organic/inorganic quantum wells in external strong magnetic fields is investigated theoretically in terms of the optimized perturbation method.The transition energies of the ground state and the low-lying excited states are evaluated as functions of the coupling constant and the strength of magnetic field in the strong coupling limit.It is shown that the transition energies increase with enhancement of the coupling constant and vary in a different manner with the strength of magnetic field.The transition energies as a function of the mass ratio ρ=me/mh are also discussed.
