ABSTRACT:
A resonant tunneling device having a one-dimensional quantum well comprises a semiconductor region capable of exhibiting one-dimensional quantization. The device comprises source and drain contact regions adjoining such semiconductor region as well as a gate contact for applying a field to such region; the device can be implemented, e.g., by methods of III-V deposition and etching technology. Under suitable source-drain bias conditions the device can function as a transistor having negative transconductance.
