We propose to establish a new novel platform for studying complex superconductivity in cuprates by designing a copper oxide plane. In this study, a new type of functional two-dimensional interface composed of copper-oxide monolayer is grown via pulsed laser deposition. By using the atomically flat TiO2-terminated SrTiO₃ substrate and reflection high-energy electron diffraction (RHEED), the deposited Strontium copper oxide (SCO) can be controlled in precise mono-layer thickness. This one-atomic-layer structure effectively generates a two-dimensional copper oxide monolayer, serving as a model system for understanding the correlated interplays and for exploring novel functionalities within an ultra-thin layer. The ultra-thin monolayer possesses promising potentials in revealing numerous undiscovered physical properties, as well as in developing next generation electronic devices. We hope to provide a novel cuprate monolayer, to study and to exhibit intriguing superconductivity.
