## Description

- description: Fabrication of two-dimensional (2D) transition-metal oxides has gained
    considerable attention due to their unique crystal structures and physical properties
    distinct from their bulk counterparts. Intercalation of foreign elements into
    the graphene/SiC(0001) interface is a possible approach for achieving this, as
    it enables the confinement and arrangement of atoms within the 2D interface. However,
    while various 2D metals and their compounds have been synthesized at the graphene/SiC
    interface, the fabrication of 2D transition-metal compounds remains challenging.
    This difficulty arises from the high reactivity of transition metals such as Fe,
    Co, and Ni, which readily form carbides and silicides with the host material.
    In this work, the fabrication of a 2D iron oxide at the graphene/SiC interface
    is demonstrated through the simultaneous intercalation of Fe and O. Direct observation
    using atomic-resolution electron microscopy revealed that the crystalline 2D iron
    oxide is encapsulated by graphene and forms a sharp interface with the SiC substrate.
    Structural analysis and Mössbauer spectroscopy suggest that the 2D iron oxide
    exhibits a wüstite-like structure. These findings provide another strategy for
    synthesizing 2D transition-metal oxides, opening new avenues for the advancement
    of 2D magnetic materials.
