The structures of boron clusters, such as flat clusters and fullerenes, resemble those of carbon. Various two‐dimensional (2D) borophenes have been proposed since the production of graphene. The recent successful fabrication of borophene sheets has prompted extensive researches, and some unique properties are revealed. In this review, the recent theoretical and experimental progress on the structure, growth, and electronic and thermal transport properties of borophene sheets is summarized. The history of prediction of boron sheet structures is introduced. Existing with a mixture of triangle lattice and hexagonal lattice, the structures of boron sheets have peculiar characteristics of polymorphism and show significant dependence on the substrate. Due to the unique structure and complex BB bonds, borophene sheets have many interesting electronic and thermal transport properties, such as strong nonlinear effect, strong thermal transport anisotropy, high thermal conductance in the ballistic transport and low thermal conductivity in the diffusive transport. The growth mechanism and synthesis of borophene sheets on different metal substrates are also presented. The successful prediction and synthesis will shed light on the exploration of new novel materials. Besides, the outstanding and peculiar properties of borophene make them tempting platform for exploring novel physical phenomena and extensive applications.

2D硼片：结构，生长以及电子和热传输性质
硼簇的结构，例如扁平簇和富勒烯，类似于碳的结构。自生产石墨烯以来，已提出了各种二维（2D）硼苯。硼苯甲片的最近成功的制造已经引起了广泛的研究，并且揭示了一些独特的性质。在这篇综述中，总结了硼苯甲片的结构，生长以及电子和热输运性质的最新理论和实验进展。介绍了预测硼片结构的历史。硼片的结构存在三角形晶格和六边形晶格的混合物，具有多态性的独特特征，并显着依赖于基底。由于独特的结构和复杂的BB键，硼苯芬片具有许多有趣的电子和热传输特性，例如强非线性效应，强热传输各向异性，弹道传输中的高导热性和扩散传输中的低导热性。还介绍了在不同的金属基材上硼烷片的生长机理和合成方法。成功的预测和合成将为新的新型材料的探索提供照明。此外，硼苯的出色和独特的性能使其成为探索新颖的物理现象和广泛应用的诱人平台。
