Local Interactions of Atmospheric Oxygen with MoS(2) Crystals

Thin and single MoS(2) flakes are envisioned to contribute to the flexible nanoelectronics, particularly in sensing, optoelectronics and energy harvesting. Thus, it is important to study their stability and local surface reactivity. Their most straightforward surface reactions in this context pertain to thermally induced interactions with atmospheric oxygen. This review focuses on local and thermally induced interactions of MoS(2) crystals and single MoS(2) flakes. First, experimentally observed data for oxygen-mediated thermally induced morphological and chemical changes of the MoS(2) crystals and single MoS(2) flakes are presented. Second, state-of-the-art mechanistic insight from computer simulations and arising open questions are discussed. Finally, the properties and fate of the Mo oxides arising from thermal oxidation are reviewed, and future directions into the research of the local MoS(2)/MoO(x) interface are provided.
