A superconducting field-effect transistor (SFET), described on pages 1461- 1462 of this issue utilizes an electric field to cause an imbalance in the electron density.
The structure shown in the above drawing is a complementary inverter, which consists of two SFETs, one in which T(c) increases with a positive bias and one in which T(c) decreases with the same bias. With a supply source of V and logic inputs of O or V, outputs are achieved of V or O, respectively, in a logic operation. Additional electric field controlled superconducting applications can be devised. For example, the channel can be a Josephson weak link or a tunnel junction in which one electrode is affected by the field and electric field control of the Josephson effect will be possible.
