Non-independent metalenes cannot maintain structural stability, but they are expected to possess extraordinary properties that provide excellent prospects for applications in physics, chemistry, and materials science. In this study, a simple physical method is used to prepare a metalene sandwiched between graphene layers. High-resolution transmission electron microscopy observation reveals Au (111) single-layer goldene intercalated with graphene monolayers. Density functional theory calculations indicate that the Au atoms in goldene are stabilized through weak interactions between graphene and Au atoms. The discovery of this structure consisting of single layers of goldene sandwiched between graphene layers suggests ideas for the preparation of such layered materials and opens up the possibilities for their wider application in physics and materials science.
