Li-doped metallic black phosphorous


Using angle-resolved photoemission spectroscopy (ARPES) we show that the surface of black phosphorus (bP) can be chemically functionalized using Li atoms which donate their 2s electron to the conduction band. First principles calculations demonstrate the metallization of phosphorene by means of Li doping filling the unoccupied antibonding pz states. The electron–phonon coupling in the metallic phase is strong enough to eventually lead to a superconducting phase at Tc = 17K for LiP8 stoichiometry. The combined theoretical and experimental study demonstrates the semiconductor-metal transition indicating a feasible way to induce a

superconducting phase in phosphorene and few-layer black phosphorus.
