Strained Freestanding single-crystal superconducting electron-doped cuprate membranes

Thin films of cuprate superconductors are easier to control in terms of doping as compared to bulk samples. However, they require specific substrates to facilitate epitaxial growth. These substrates are often incompatible with materials used in electronic applications. Furthermore, it is challenging to separate the substrate's properties from the material of interest. Previously we have demonstrated the fabrication of an electron-doped cuprate membrane and showed that the membrane has a coherent crystal structure. Furthermore, the superconducting properties of the membrane post-liftoff closely resemble those of the thin films pre-lift-off. In the current talk we will present results on strained cuprate membranes, with transport and SQUID data across different strain and material doping levels.
