Abstract: We investigate the transition from static to dynamic electric field domains in a doped GaAs/AlAs superlattice. We show that a transverse magnetic field and/or the temperature can induce current self-oscillations. This observation can be attributed to the negative differential resistance effect. Transverse magnetic field and the temperature can increase the negative differential resistance of a doped superlattice. A large negative differential resistance can lead to an unstable electric field domain in a certain range of de bias.
