摘要：
A new mechanism for self-generated current oscillations in modulation-doped semiconductor heterostructures under parallel conduction is proposed. It is based upon the nonlinear dynamics of real-space electron transfer and delayed dielectric relaxation of the interface potential barrier resulting from the space charge in the doped AlGaAs layer. From our simulations we predict current oscillations in the 20-80 GHz range under dc bias.
