title: A Metal-Insulator Transition of the Buried MnO2Monolayer in Complex Oxide Heterostructure.
abstract: A novel artificially created MnO2monolayer system is demonstrated in atomically controlled epitaxial perovskite heterostructures. With careful design of different electrostatic boundary conditions, a magnetic transition as well as a metal-insulator transition of the MnO2monolayer is unveiled, providing a fundamental understanding of dimensionality-confined strongly correlated electron systems and a direction to design new electronic devices.
