Abstract

In article number 2100328, Maciej Rogala, Stanislaw Sokolowski, Robert Szoszkiewicz, and co-workers investigate chemical origins of the MoOx species appearing on single MoS2 flakes due to their oxidation in dry and humid air. MoOx species on the oxidatively etched MoS2 surface are shown to originate from loosely surface-bound (MoO3)n (n > 0) single clusters with an average height of 0.32 ± 0.05 nm. Their presence has been confirmed topographically and chemically via combined AFM, XPS, and XAS studies.
