摘要

二维过渡金属二硫族化合物(TMDCs)是具有高度各向异性的层状半导体,通式为ME2 (M =金属,E =硫,硒或碲)。目前该领域的许多研究都集中在催化和能源应用上;它们也吸引了下一代晶体管和光电子器件的极大兴趣。后者的高科技应用对单层和少层材料的化学计量学、结晶度、形貌和电子性能提出了严格的要求。作为一种基于溶液的工艺,其中材料专门在电极表面生长,电沉积作为一种易于扩展的、区域选择性生长工艺提供了很大的希望。本综述探讨了TMDC电沉积的最新技术,强调了前驱体(或前驱体)、溶剂和电极设计的选择,以及新颖的“器件就绪”电极几何形状,如何影响其形态和性能,从而实现超薄、高度各向异性的2D TMDC的直接生长,并为未来的发展提供了很大的空间。

Molecular precursors for the electrodeposition of 2D-layered metal chalcogenides.

Two-dimensional transition metal dichalcogenides (TMDCs) are highly anisotropic, layered semiconductors, with the general formula ME2 (M = metal, E = sulfur, selenium or tellurium). Much current research in this field focusses on TMDCs for catalysis and energy applications; they are also attracting great interest for next-generation transistor and optoelectronic devices. The latter high-tech applications place stringent requirements on the stoichiometry, crystallinity, morphology and electronic properties of monolayer and few-layer materials. As a solution-based process, wherein the material grows specifically on the electrode surface, electrodeposition offers great promise as a readily scalable, area-selective growth process. This Review explores the state-of-the-art for TMDC electrodeposition, highlighting how the choice of precursor (or precursors), solvent and electrode designs, with novel 'device-ready' electrode geometries, influence their morphologies and properties, thus enabling the direct growth of ultrathin, highly anisotropic 2D TMDCs and much scope for future advances.
