We have analyzed the electronic current density and the charge stored in the well in a resonant tunneling double barrier heterostructure in the presence of an external electromagnetic field. We studied the processes of charging and discharging of the well in the boundaries of the bistability region, and we calculated the transient times as a function of the field parameters. We found that the width of the bistability region is reduced by the external field. Moreover, dynamical instabilities in the charge stored in the well may be triggered by the oscillating field.
