✦ Synopsis

We study nonlinear phenomena in double barrier heterostructures. Systems in 3D under the effect of an external magnetic field along the current and 1D systems are analyzed. Nonlinearities are reflected in the I -V characteristic curve as bistabilities, instabilities and time-dependent oscillations of the currents. The nature of the nonlinear behavior depends upon the parameters that define the system.
