A novel way to grow MoS2 on a large scale with uniformity and in desired patterns is developed. We use Au film as a catalyst on which [Mo(CO)6] vapor decomposes to form a Mo‐Au surface alloy that is an ideal Mo reservoir for the growth of atomic layers of MoS2. Upon exposure to H2S, this surface alloy transforms into a few layers of MoS2, which can be isolated and transferred on an arbitrary substrate...
Muster aus großen MoS2‐Atomlagen wurden von H. C. Choi et al. in ihrer Zuschrift auf S. 1290 ff. aufgebaut. Der chemische Prozess lässt sich mit dem Lebensweg eines Falters vergleichen: Nach der Abspaltung von CO‐Liganden wandern Mo‐Atome wie Raupen umher. Bald bilden sie eine Oberflächenlegierung, in der sie von der Außenwelt abgeschirmt sind wie in einer Puppe. Bei H2S‐Behandlung treten sie in veränderter...
