POSCAR for two dimensional sheets

Hi everyone,
I am very new to VASP. In order to study the properties of two-dimensional sheets, I need the POSCAR for a particular sheet. I got POSCAR file using materialproject.org. But I have a doubt whether I can use the coordinates as such or not?

Thanks in Advance.

Hi vaspuser,

Is there something specific that’s wrong with the POSCAR you’re referring to? It would help us to have a more specific example of your problem.
