最近,二维(2D)金属MoN在实验中成功制备。其内在特性仍有待从理论上深入探讨。通过第一性原理计算研究了 MoN 单层的固有性质。发现了最外层 Mo 和 N 表面的独特几何特性。我们预测 N 表面的功函数高达 6.3 eV,这表明 2D MoN 在半导体行业的应用具有巨大价值。我们进一步探索了 2D MoN 作为锂离子电池负极材料的潜力。研究发现,单个Li原子在MoN表面的吸附能可低至-4.04 eV。小扩散势垒(0.41 eV)和高理论最大容量(406 mAh·g−1,包含多层吸附)都意味着2D MoN具有出色的锂离子电池性能。
Recently, two-dimensional (2D) metallic MoN was manufactured successfully in experiment. Its intrinsic properties remain to be explored theoretically, in depth. The intrinsic properties of a MoN monolayer are investigated by first-principles calculations. The distinct geometric properties of the outermost Mo and N surfaces are discovered. We predict an extremely high work function of 6.3 eV of the N surface, which indicates the great value of the 2D MoN for application in the semiconductor industry. We further explore the potential of 2D MoN as anode material for lithium-ion batteries. It is found that the adsorption energy of a single Li atom on an MoN surface can be as low as −4.04 eV. The small diffusion barriers (0.41 eV) and high theoretical maximum capacity (406 mAh · g−1 with the inclusion of multilayer adsorption) all imply an outstanding lithium-ion battery performance by 2D MoN.
