摘要
As a kind of specially modified chemical vapor deposition (CVD), atom ic layer deposition (ALD) has long been used to fabricate thin films. The self-limiting reaction of ALD endows the films with excellent uniformity and precise controllability. The thickness o f the tilms obtained by ALD can be controlled in an atom ic scale (0.1 nm) on a large-area substrate even with complex structures. Therefore, it has recently been employed to produce the two-dimensional (2D) materials like MoS2. In this mini-review, the research progress in ALD MoS2 is firstly summarized. Then the influences of precursors, substrates, temperature, and post-annealing treatm ent on the quality of ALD-MoS2 are presented. Moreover, the applications of the obtained MoS2 as an electrochemical catalysator are also described. Besides the perspective on the research of ALD of MoS2, the remaining challenges and promising potentials are also pointed out.
作为一种特殊的化学气相沉积技术,原子层沉积在薄膜制造领域得到广泛的应用.得益于自限制化学反应,原子层沉积所制备的薄膜具有优异的均匀性且精确可控.基于原子层沉积技术,在复杂、大面积基底上制备的薄膜厚度可以控制在原子尺度精度(0.1 nm).因此,它已经被用来制备二维MoS2材料.本综述首先介绍了原子层沉积MoS2薄膜的相关研究进展,然后就前驱体、衬底、温度和退火等工艺参数对薄膜质量的影响进行了分析,最后对原子层沉积制备的MoS2在电化学催化领域的应用进行了评论.该综述不仅回顾了原子层沉积MoS2的研究进展,而且指出了尚存的挑战和突破的希望.
