Modeling MoS2 on Graphene using FDTD's 2D structures
Simulating MoS2 (0.615nm thick) on a layer of Graphene requires an extremely small mesh when using standard 3D material models. I think the 2D object and material model (i.e. https://support.lumerical.com/hc/en-us/articles/360042244874-Graphene-surface-conductivity-material-model) are better for this type of simulation. I get sensible results for MoS2 and Graphene on their own, but combining them in a single simulation doesn't work.
Note: I took the values for dielectric constant of MoS2 from http://journals.aps.org/prb/pdf/10.1103/PhysRevB.90.205422
