Abstract
Time dependent phenomena associated to charge transport along double barrie r heterostructures are studied. Systems in 3D under the effect of an extern al magnetic field along the current and 1D systems are analyzed. Together w ith static multistabilities in the negative resistance region of the I-V ch aracteristic curve, we found self-sustained time dependent current and char ge oscillations. The nature of this oscillatory behavior depends upon the p arameters that define the system.
