Growth of Single Unit-Cell Superconducting La${}_{2-x}$Sr${}_x$CuO${}_4$ Films

A. Rufenacht, P. Chappatte, S. Gariglio +4

We have developed an approach to grow high quality ultrathin films of La${}_{2-x}$Sr${}_x$CuO${}_4$ with molecular beam epitaxy, by adding a homoepitaxial buffer layer in order to mini…
