New two-dimensional (2D) copper monoxide
located at the pore in
a bilayer graphene matrix is investigated in both theoretical and
experimental ways. Strict analysis of the lattice stability with respect
to the magnetic state reveals that the CuO monolayer displays an antiferromagnetic
rectangular structure as a favorable state. It is shown that 2D CuO
can be confined in a bilayered graphene pore terminated with Cu atoms
forming spin-polarized states on the graphene/CuO interface. It is
found that the co-presence of Cu and O atoms around the bilayered
graphene edge plays an essential role in the 2D CuO formation process.
