Abstract: PROBLEM TO BE SOLVED: To provide a device which can improve the performances of a switching device and a logic device by increasing the PVR. SOLUTION: In a resonant tunneling electronic device, a plurality of quantum barrier layers 2, 4, and 6 and quantum well layers 3 and 5 are alternately laminated upon another between an emitter 1 and collector 7 so that the height of each quantum barrier can gradually become higher and, at the same time, the width of each quantum well formed between each quantum barrier can gradually become narrower. In addition, when the quantum barriers and wells are formed so that their heights can become asymmetrical, the structures of the quantum barriers and wells can be adjusted and a tunneling current can be adjusted easily.
