摘要：

The effect of interdiffusion on hydrogen-like donor impurity binding energy in a multiple quantum well structure composed of 9 wells and 8 barriers is investigated. The effect of external magnetic field along the growth direction is taken into account as well. The obtained results show that the simultaneous effect of interdiffusion and the external magnetic field give a great opportunity of purposeful manipulation of binding energy and the character of the diffusion effect on binding energy strongly depends on the position of impurity center.
