Improving the Josephson energy in High-T${}_c$ superconducting junctions for ultra-fast electronics

H. Navarro, M. Sirena, N. Haberkorn

We report the electrical transport in vertical Josephson tunnel junctions (area 400 $\mu m$${}^2$) using GdBa${}_2$Cu${}_3$O${}_7$${}_{-\delta }$ electrodes and SrTiO${}_3$ as an insulating barrier (wi…
