ABSTRACT:
The present invention provides a resonant tunneling electronic device having a plurality of nearly decoupled quantum barrier layers and quantum-well layers alternatively formed between an emitter layer and a collector layer, and has a stacked structure in such a manner that in the order of their stack the heights of the quantum barriers are gradually increased, and the widths of the quantum-wells interposed between the quantum barrier layers are gradually decreased, so that electron resonant tunneling through the aligned quantum with confined states under the application of external bias can occur.
