Abstract
A Josephson triode is a three-terminal superconductive device integrated with three Josephson devices. One of the three devices is used as a local oscillator and the triode can be used as a heterodyne detector. In such an application, since a Josephson device is used as a local oscillator, the frequency of the oscillator can be varied continuously, and the thermal noise is extremely low. However, there is no experimental report regarding the Josephson triode. In this study, microcontact Josephson triodes were fabricated by the self-alignment process technique using electron beam exposure. This device showed a negative resistance in the current-voltage characteristic of the converter junction.
