Atomically thin ternary compounds/alloys of boron, nitrogen and carbon have generated significant excitement as they provided the first instance of a tuneable 2D material that affords rich physics as well applications potentials. Interestingly, the crucial role and the possible inclusion of oxygen in the 2D-BNC lattice have never been investigated. Here, we present the first report on an atomically thin quaternary alloy of boron, nitrogen, carbon and oxygen, 2D-BNCO. Our experiments suggest and theoretical calculations corroborate stable configurations of a planar honeycomb 2D-BNCO lattice. We observed the growth of micron-scale 2D-BNCO domains within a graphene-rich matrix, and were able to control their area coverage and relative composition by varying the ratio of oxygen content in the growth setup. The introduction of oxygen into the BNC system induces a rich variety of electronic, optical, and magnetic properties.
