少层黑磷(FLBP)是一种新近发现的二维半导体材料，由于其在电子和光电子领域的巨大应用潜力，引起了科技界的广泛关注。然而，FLBP薄片与周围物种的反应性限制了其直接应用。在各种常温下钝化FLBP的方法中，将FLBP片层与稳定的基质混合在一起的纳米复合材料可能是最有前途的工业应用方法之一。在这里，我们报道了一种简单的一步法，在液相中批量生产空气稳定的FlBP/磷脂纳米复合材料。结果表明，所制备的纳米复合材料对载流子具有超低的隧道势垒，这可以用EFros-Shklovskii变程跳跃机制来描述。由这种大规模生产的FlBP/磷脂纳米复合材料制成的器件在环境条件下表现出高度稳定的电导和光电响应，表明其在电子学和光电子学领域都具有广阔的应用前景。这种方法也可以推广到由FeSe、NbSe2、WTe2等其他气敏2D材料组成的纳米复合材料的批量生产。
Few-layer black phosphorus (FLBP), a recently discovered two-dimensional semiconductor, has attracted substantial attention in the scientific and technical communities due to its great potential in electronic and optoelectronic applications. However, reactivity of FLBP flakes with ambient species limits its direct applications. Among various methods to passivate FLBP in ambient environment, nanocomposites mixing FLBP flakes with stable matrix may be one of the most promising approaches for industry applications. Here, we report a simple one-step procedure to mass produce air-stable FLBP/phospholipids nanocomposite in liquid phase. The resultant nanocomposite is found to have ultralow tunneling barrier for charge carriers which can be described by an Efros–Shklovskii variable range hopping mechanism. Devices made from such mass-produced FLBP/phospholipids nanocomposite show highly stable electrical conductivity and opto-electrical response in ambient conditions, indicating its promising applications in both electronic and optoelectronic applications. This method could also be generalized to the mass production of nanocomposites consisting of other air-sensitive 2D materials, such as FeSe, NbSe2, WTe2, etc.
