Abstract
We study the electric control of the Josephson current flowing in a clean triplet superconductor (TS) junction with a two-dimensional electron gas (2DEG) layer between two leads. The Rashba spin-orbit coupling (RSOC) is considered in the 2DEG region and its strength can be altered by an external electric field. Since the TS Cooper pairs can achieve a spin precession phase due to the pseudomagnetic field from RSOC when they travel in the 2DEG region, the Josephson current exhibits a regular 0-π oscillation, abrupt current reversal effect, and an unusual temperature dependence. Our findings may provide a purely electric means to control the Josephson current.
