二维材料在柔性电子中的研究现状与发展

Research Status and Development of Two-dimensional Materials in Flexible Electronics

基于柔性电子器件对柔性衬底的要求,衬底应足够薄且达到足够的韧性度。二维材料因原子级的厚度表现出极强的发展潜力。至今,石墨烯、硅烯、磷烯和二维过渡金属硫族化合物是二维材料的典型代表,其结构、特性和制备方式影响着它们在柔性电子器件中的应用范围。本文将以上几种二维半导体材料为阐述目标,分别从其合成、改性以及二维纳米结构控制等因素出发,综述了他们在柔性有机发光二极管、有机薄膜晶体管以及场效应晶体管中的应用现状以及在未来亟需解决的问题。

Based on the requirements of flexible electronic devices on flexible substrates,the substrate should be thin enough and achieved sufficient toughness.Two-dimensional materials show extremely strong development potential due to atomic thickness.So far,graphene,silene,phosphorene and two-dimensional transition metal chalcogenide compounds are typical representatives of two-dimensional materials.Their structure,characteristics and preparation methods affect their application in flexible electronic devices.In this review,the above mentioned two-dimensional semiconductor materials are employed as elaboration goals,and their application statuses in flexible organic light-emitting diodes,organic thin-film transistors and field-effect transistors are reviewed based on their synthesis,modification and two-dimensional nanostructures controlling.The problems that need to be solved urgently in the future are described in detail also.
