摘要
Calculations of the electron transmission through a single nonabrupt GaAs/AlxGa1-xAs barrier subjected to an electric field have been performed. The electron transmission is shown to be strongly dependent on the interface potential and electron effective mass. The overall reduction of the electron transmission due to the electric field is smaller for wide interfaces. Peak-to-valley transmission ratios change considerably with the interfacial width, as well as with the scheme used to describe interfaces.
