Figure 3From: Adsorption of gas molecules on monolayer MoS2 and effect of applied electric fieldCharge density difference plots. Charge density difference plots for (a) O2, (b) H2O, (c) NH3, (d) NO, (e) NO2, and (f) CO interacting with monolayer MoS2. The red (green) distribution corresponds to charge accumulation (depletion). The isosurface is taken as 5 × 10-4e/Å3. The direction and value of charge transfer are also denoted.Back to article page
