摘要:

超薄的过渡金属碳氮化合物MXenes, 作为一大类新兴二维(2D)材料, 是当前材料研究热点方向之一。自2D材料发现至今已有近20年, 以石墨烯、过渡金属硫族化合物、黑磷等为代表的2D材料在微纳电子领域经历了相对广泛且深入的研究, MXenes自2011年诞生以来在微纳电子领域的研究也方兴未艾。MXenes拥有丰富的元素结构组成和独特的物理化学特性(表面亲水性、功函可调、官能团可调、电和离子快速传输特性、表面离子激元、光热电、电磁吸收等), 使其在微纳电子领域具有潜在的应用前景。Alshareef课题组近几年致力于将MXene引入到微纳电子领域, 并在2019年用MXetronics来定义MXene电子学这一新兴的学术领域。本文简要总结和评价了该领域的代表性进展, 梳理了包括微电子级的合成、加工、物性探索和器件应用等方面面临的挑战, 最后指出一些关键的研究方向和尚未探索的细分领域。

Abstract:

Atomic-thin transition metal carbonitrides (MXenes), as an emerging class of two-dimensional (2D) materials, become a highly active research topic. Since the discovery of graphene nearly 20 years ago, many 2D materials (graphene, transition metal dichalcogenides, and black phosphorus) have been extensively studied in the field of micro-nano electronics. However, research on MXenes-based micro-nano electronics has just begun. MXenes exhibit rich elemental compositions and unique physicochemical properties, such as hydrophilicity, tunable work function, adjustable functional groups, fast ion and electron transport, superconductivity, surface plasmons, photo- thermo-electricity, and electromagnetic absorption, and some MXenes even possess high conductivity. These characteristics make MXenes hold great potential for device applications at the microscale or even nanoscale. In recent years, the Alshareef research group has been dedicated to bringing MXenes into the field of micro-nano electronics and has defined the emerging academic field of MXene electronics, known as MXetronics, in 2019. This perspective briefly summarizes and evaluates representative research progress in this field, including the challenges in synthesis, processing, property investigation, and device applications at the microelectronic level. Furthermore, we will propose several key research directions and unexplored subfields in this area.
