Abstract We study the electronic energy levels and probability distribution of vertically stacked self-assembled InAs quantum disks system in the presence of a vertically applied electric field. This field is found to increase the splitting between the symmetric and antisymmetric levels for the same angular momentum. The field along the direction from one disk to another affects the electronic energy levels similarly as that in the opposite direction because the two disks are identical. It is obvious from our calculation that the probability of finding an electron in one disk becomes larger when the field points from this disk to the other one.
