Abstract
We propose a set of boundary conditions for electron envelope functions at GaAs/AlAs (001) heterointerfaces so as to take into account Γ- X mixing in the effective mass method. The proposed conditions enable one to obtain the dependence of the mixing effect upon the parity of monomolecular layer numbers in (GaAs) N (AlAs) M superlattices. The electron transmission spectra of GaAs(AlAs) M GaAs single barrier structures are calculated in the generalized effective-mass approximation. It is shown that the spectral fine structure depends essentially upon the parity of M. The low-temperature d.c. current-voltage characteristics of the single-barrier structure is derived taking into account the camel-back X-band structure in bulk AlAs and GaAs.
