The influence of nonabrupt interfaces in the high electric field
resonances of single AlxGa1-xAs barriers in GaAs is studied. The
resonances are considerably smoothed when interfacial widths are as
small as two GaAs lattice parameters. Several resonances in the
transmission coefficient of a 0.154 eV electron through a non-abrupt
AlxGa1-xAs single barrier in GaAs, with height of 240 meV and 200
Angstrom of width, can even disappear if interfacial widths of four GaAs
lattice parameters are considered. Interface effects are shown to be
more important for heavy holes than for electrons.
