本文简要综述了反双极晶体管（AAT）的最新研究进展。到目前为止，各种半导体材料，如二维（2D）原子层、碳纳米管和有机半导体（OSCs），已被用作AAT通道。在这些材料中，我们在本综述中重点关注OSCs，通过与2D材料的比较，强调其在可加工性、可扩展性和器件可设计性方面的优势。aat的独特性可归因于其独特的电学特性：Λ-shaped传递曲线和在光电应用中的高潜力。首先，从特征器件结构的角度讨论了载流子输运的基本机理，其关键因素是晶体管沟道处的pn异质结。然后，我们强调了通过实验和理论模拟进行集体和系统调查的重要性。其次，回顾了ATT的应用，包括多值逻辑（MVL）电路及其光响应性和柔性基板上的应用。尽管有机电子具有各种优点，如机械灵活性，重量轻，溶液可加工性和成本效益，但直到最近，人们才认识到有机电子在集成密度和数据处理能力方面存在弱点，因为它们与传统光刻工艺不兼容。然而，有机aat似乎提供了克服这些弱点的方法，从而在有机电子学领域开辟了一个新的前沿。
This paper briefly reviews recent progress in antiambipolar transistor (AAT) development. A variety of semiconducting materials, such as two-dimensional (2D) atomic layers, carbon nanotubes, and organic semiconductors (OSCs), have been employed as AAT channels thus far. Among these materials, we focus on the OSCs in this review, with emphasis on their advantages in terms of processability, scalability, and device designability, through comparison with their 2D counterparts. The uniqueness of AATs can be ascribed to their distinctive electrical properties: the Λ-shaped transfer curve and high potential for use in optoelectronic applications. First, the fundamental mechanism of the carrier transport is discussed in terms of the characteristic device configuration, the key element of which is the PN-heterojunction at the transistor channels. Then, we underline the importance of collective and systematic investigations through experiment and theoretical simulation. Second, the ATT applications are reviewed, including multivalued logic (MVL) circuits along with their optical responsivity and those on flexible substrates. Despite their various advantages, such as mechanical flexibility, light weight, solution processability, and cost-effectiveness, organic electronics have, until recently, been recognized to have weak points in terms of integration density and data processing capability, because of their incompatibility with conventional lithographic processes. However, organic AATs appear to offer means to overcome such weaknesses, and thereby open a new frontier in the field of organic electronics.
