Abstract

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. Here, we demonstrate the fabrication of an electron-doped cuprate membrane. We show that the membrane has a coherent crystal structure. Furthermore, the superconducting properties of the membrane postliftoff closely resemble those of the thin films preliftoff, as revealed by a scanning superconducting quantum interference device (SQUID) microscope. Such membranes pave the way for designing new material properties and incorporating complex superconducting materials into typically incompatible electronic devices.
