摘要

二维(2D)材料在纳米级厚度上具有广泛的独特特征,吸引了科学界的关注。尽管二维材料的探索研究取得了巨大进步,但对二维电输运和载流子动力学的了解仍处于起步阶段。因此,我们在此着重介绍二维材料的电子能带结构、电子传输、介电常数和载流子迁移率等电学特性。二维材料的原子薄度使得场效应晶体管(FET)的规模大幅扩大,短沟道效应降低,尽管高性能、低电压器件运行需要很强的载流子迁移率。我们在此还讨论了影响二维材料的因素,这些因素很容易提高这些材料在各种应用中的活性。目前,二维材料因其电子带结构的广泛性而被广泛应用于最先进的电子和光电设备中。与传统的体半导体相比,二维材料为设计新型 p-n 结器件拓扑结构提供了前所未有的自由度。我们还介绍了众多二维 p-n 结,如同位结和异位结,包括混合维结。最后,我们讨论了未来的问题和潜力。

Electronic properties of 2D materials and their junctions

With an extensive range of distinctive features at nano meter-scale thicknesses, two-dimensional (2D) materials drawn the attention of the scientific community. Despite tremendous advancements in exploratory research on 2D materials, knowledge of 2D electrical transport and carrier dynamics still in its infancy. Thus, here we highlighted the electrical characteristics of 2D materials with electronic band structure, electronic transport, dielectric constant, carriers mobility. The atomic thinness of 2D materials makes substantially scaled field-effect transistors (FETs) with reduced short-channel effects conceivable, even though strong carrier mobility required for high performance, low-voltage device operations. We also discussed here about factors affecting 2D materials which easily enhanced the activity of those materials for various applications. Presently, Those 2D materials used in state-of-the-art electrical and optoelectronic devices because of the extensive nature of their electronic band structure. 2D materials offer unprecedented freedom for the design of novel p-n junction device topologies in contrast to conventional bulk semiconductors. We also, describe the numerous 2D p-n junctions, such as homo junction and hetero junction including mixed dimensional junctions. Finally, we talked about the problems and potential for the future.
