Theory of traveling filaments in bistable semiconductor structures
Pavel Rodin
We present a generic nonlinear model for current filamentation in semiconductor structures with S-shaped current-voltage characteristics. The model accounts for Joule self-heating…

Lateral current density fronts in asymmetric double-barrier resonant-tunneling structures
Pavel Rodin, Eckehard Schoell
We present a theoretical analysis and numerical simulations of lateral current density fronts in bistable resonant-tunneling diodes with Z-shaped current-voltage characteristics. T…
