Web(SEM). All lms produced were found to have similar surface morphology (Fig. 2d–f and S5†); the surface of the lms consist of partially-stacked 2D-nanosheets with lateral dimensions between 200–600 nm. Nanosheets were deposited onto lacey carbon grids for (scanning)transmissionelectronmicroscope((S)TEM)imaging. WebMar 1, 2024 · Understanding the thermochemical stability of MoS2 is essential since these devices generate heat and are susceptible to oxidative environments. Herein, we show the promoting effect of molybdenum oxides (MoOx) particles on the thermal oxidation of MoS2 monolayers employing operando XAS, ex-situ SEM, and XPS.
