Abstract
It is investigated how the interfacial growth pattern changes the
transmission properties of graded GaAs/AlxGa1-xAs double-barriers. Five
interfacial growth patterns are studied, all of them representative of
interfacial alloy variations that can be the result of different growth
techniques and growth conditions of the interfaces. It is shown that the
transmission resonances are shifted toward low energies in comparison to
those of an abrupt GaAs/AlxGa1-xAs double-barriers. The shift increases
with the interface width and with the order of the resonance, and
depends on the type of growth pattern. (C) 1998 Elsevier Science BN. All
