We propose to establish a new novel platform for studying complex superconductivity in cuprates by designing a CuO₂ monolayer. 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 SrCuO₂ (SCO) can be controlled in precise mono-layer thick. This one-atomic-layer structure effectively generates a two-dimensional CuO₂ mono-layer, 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 simple model system, a novel cuprate monolayer, to study and to exhibit intriguing superconductivity.
