| Abstract: | A correlation of AES and work function measurements of Fe and Ni on MoS2 indicated that, near room temperature of MoS2 and low coverage, Fe and Ni formed islands. With increasing coverage the Fe-islands were developed to 3-D small particles, while Ni-islands needed higher temperature for this development. The average size and density of the particles depended on the substrate temperature. Beyond a certain size the Fe-particles began to act catalytically on an interaction of the subsequently deposited Fe with S atoms of the top layer of MoS2. The Ni particles remained clean up to 800 K and did not interact with S. |
