Difference between building interface and heterostructure

[physics]

Hi everyone,

I want to know if building interface and hetero structure are same thing or different? I want to create a hetero structure but the tutorial is all about building interface. Please advise.

Thanks

Yes, they are same.
Interface is used to create heterostructure.
Now depends if you are making in-plane (mostly for 2D materials) or vertical heterostructure (for 2D/3D materials).
I am guessing your system is 3D?

Thanks for your reply. My system is 3D.
