超薄的过渡金属碳氮化合物MXen.s,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,MXen.s自2011年诞生以来在微纳电子领域的研究也方兴未艾。MXen.s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MXen.引入到微纳电子领域,并在2019年用MXetron.cs来定义MXen.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。
