Abstract

X-ray Photoelectron.pectroscopy (XPS) and Conversion Electron M6ssbauer bpectroscopy (CEMS) were used to examine iron that was deposited on the basal plane of MoS2 single crystals and subjected to vacuum annealing, oxidizing, and reducing environments. Iron either intercalated into the MoS2 structure or formed oriented iron sulfides depending on the level of excess sulfur in the MoS2 structure. CEMS data demonstrated that iron sulfide crystal structures preferentially aligned with respect to theMoS2 basal plane and that alignment, and potentially adhesion, could be variedby appropriate high temperature annealing procedures.
