Abstract

AlAs/GaAs/AlAs RTDs(Resonant Tunneling Diodes) are fabricated and current-voltage properties of them are measured. At room temperature, peak to valley ratio is 2.4 NOT.AND.OR logic gates and Flip-Flop are fabricated using the bistable characteristics of RTDs. Although NOT.AND.OR logic gates need 5~8 transistors. only one RTD is sufficient to fabricate the logic gates. Since the switching time is very short(<10$^12$sec), it is possible to drive the semiconductor circuits fast and integrate them very large. And it is convinced the possibility of integrating RTDs to multilevel logic circuits by observing two peaks of similar current in the serial connection of two RTDs.
