磷烯是一种新型的二维元素半导体材料，具有不同于其他二维材料的独特的物理和化学性质。磷烯在纳米/光电子和热电领域中的应用日益广泛，迫切需要对其热输运性质进行全面的研究。本文从理论和实验两个方面综述了单层磷烯、多层磷烯（纳米膜）和块体黑磷的热输运性质，概括了从单层到块体形式的整体热导率趋势。磷烯的热导率报告的差异的机制进行了讨论，通过审查不同的功能和截止距离的热输运评价的效果。这篇评论，然后提供了基本的洞察磷烯的热输运通过审查的作用，驱动巨声子非谐性和长程相互作用的共振键。此外，通过讨论应变和衬底的影响，以及磷烯基异质结构和纳米带，综述了磷烯的非本征热导率。本文从理论计算和实验测量两个方面综述了磷烯热输运的研究进展，对磷烯基高效纳米电子学的设计和发展具有重要意义。
Phosphorene, a novel elemental 2D semiconductor, possesses fascinating chemical and physical properties which are distinctively different from other 2D materials. The rapidly growing applications of phosphorene in nano/optoelectronics and thermoelectrics call for comprehensive studies of thermal transport properties. In this Review, based on the theoretical and experimental progresses, the thermal transport properties of single-layer phosphorene, multilayer phosphorene (nanofilms), and bulk black phosphorus are summarized to give a general view of the overall thermal conductivity trend from single-layer to bulk form. The mechanism underlying the discrepancy in the reported thermal conductivity of phosphorene is discussed by reviewing the effect of different functionals and cutoff distances on the thermal transport evaluations. This Review then provides fundamental insight into the thermal transport in phosphorene by reviewing the role of resonant bonding in driving giant phonon anharmonicity and long-range interactions. In addition, the extrinsic thermal conductivity of phosphorene is reviewed by discussing the effects of strain and substrate, together with phosphorene based heterostructures and nanoribbons. This Review summarizes the progress of thermal transport in phosphorene from both theoretical calculations and experimental measurements, which would be of significance to the design and development of efficient phosphorene based nanoelectronics.
