中文摘要	we study the oscillator strengths of the optical transitions of the vertically stacked self-assembled inas quantum discs. the oscillator strengths change evidently when the two quantum discs are far apart from each other. a vertically applied electric held affects the oscillator strengths severely, while the oscillator strengths change slowly as the radius of one disc increases. we also studied the excitonic energy of the system, including the coulomb interaction. the excitonic energy increases with the increasing radius of one disc, but decreases as a vertically applied electric field increases.
