Analog of the Gunn Effect in Heterostructure with Two Tunnel-Coupled Quantum Well
Abstract
Electron transport in heterostructure with two tunnel-coupled quantum well has been numerically investigated under condition of strong non-one-dimensionality of electric field in the structure. It is shown for the first time an ability of the effect in such heterostructures which is similar to the Gunn effect in bulk semiconductor. The effect is conditioned by the electron tunneling transition between quantum wells with different mobility and is characterized by formation of the strong field domain and the negative differential conductivity region on current-voltage characteristic.
