In the resonant tunneling diode incorporating a wide one-sided spacer layer, an oscillation picture has been studied in both polarities of the applied voltage in high magnetic field. The results lead to the conclusion that the interference between the electron waves running in the forward direction and the ones reflected at some potential step can occur in both the emitter and collector regions. The characteristic lengths corresponding to the path of the ballistic motion of electrons were estimated. An exchange enhancement of the electronic g-factor in two-dimensional systems was observed.
