Graphene sandwiched by hexagonal boron nitride

  Hello! I would like to build structures for simulation in the range of 300-1600nm where there is graphene between two layers of hBN (hexagonal boron nitride). I know that hBN can be understood as a 2D material, but how do I introduce both models into the simulation, considering they are consecutive?

  unfortuately, the current algorithm does not supprt two 2D material attached together, as it will use only one 2D material based on the material priority rule.
  It is likely that you have to make one of the two 2D materials into bulk, 3D material with resonable thickness, and convert its surface conductivity into permitivvity. For example graphene:

  you can find it in the material daabase.
