In the case of an impurity, the time evolution is richer. The impurity can oscillate between the two empty sites which form the antisoliton, and ...

The different band gaps of GaAs and AlGaAs can be used to form a potential well, in which the electron gas resides. The small difference in lattice constants between GaAs and AlGaAs insures that there is a ...
