The electronic structure of different (001) (AlAs)(m)(InAs)(1)(GaAs)(m
) multilayer structures is studied. We have thus seen the influence of
the relative thicknesses of the constituent materials and of the posi
tions of the InAs principal layers in the multilayer structures on the
energy eigenstates and on their spatial localization. The calculation
s are based on an sp(3)s empirical tight-binding model and on the sur
face Green function matching method. (C) 1998 Elsevier Science B.V. Al
