Is it possible to simulate a 2D material in Geant4?

Hi everyone, for a uni project we’re exfoliating a certain material and checking its X-ray attenuation potential. For this I’m trying to simulate the same setup in Geant4, however I haven’t been able to find any information on wether or not it’s possible to create a 2D material in Geant4 or add 2D material properties to a material. We’re thinking the reason 2D materials are good for X-ray attenuation is due to their huge surface area and their high optical and UV absorbtion. Does someone have an idea on how to add these properties? Thank you

It isn’t possible to create a volume that is only 2D, but you can create a material that is very thin in one axis.

G4Box* solidThinVolume = new G4Box(“solidThinVolume”, 10.0 * cm/2.0, 10.0 * cm/2.0, 1.0 * um/2.0);

The above code creates a volume that is 10 cm by 10 cm in X and Y but only 1 um thick in Z.
