Double Barrier Resonant Tunneling

We study the resonant tunneling in symmetric GaAs/AlxGa1-xAs/InyGa1-yAs double-barrier resonant-tunneling structures. Effects of three factors on the resonant tunneling are simulated and discussed. On increasing the barrier height, the decrease of current density is attributed to the interplay between the increase of the supply function of available electrons and the rapid decrease of the transmission coefficient through the device area, and the lowest Indium content for realizing the zero-bias resonant tunneling increases. With the increase of the barrier (well) width, the decrease of the current density can be explained by the fact that both the supply function and the transmission coefficient decreases, and the lowest Indium content meeting the zero-bias resonant condition decreases.
