Evidence of Josephson junction behavior in top-gated LaAlO${}_3$-SrTiO${}_3$

Varada V Bal, Manan M Mehta, Sangwoo Ryu +4

We demonstrate top-gate tunable Josephson junction like behavior in the two dimensional electron gas at the LaAlO${}_3$-SrTiO${}_3$ interface. A combination of global back-gating and l…
