Abstract

Researchers conducted a study to create a single metal-oxide plane as a 2D monolayer through interface engineering. This 2D oxide monolayer could be obtained at the heterostructure similar to the case of a single-unit-cell manganite ultrathin film sandwiched between two neighboring complex oxides. This study delivered a generic approach to study the dimensional confinement of strongly correlated electron systems and provides a direction to design new electronic devices. The MnO2 monolayer was chosen as a model system, since the mixture of Mn4+ and Mn3+ cations in these oxide planes dominated the novel physical phenomena of colossal magnetoresistance manganites.
