surf_energy_error(xc_func, atom_no, valence, volume)[source]

Computes the Unit Surface Energy Error for given functional and atom.

Parameters: xc_func – Exchange Correlation Functional. Options are “LDA”, “PBE”, “PW91” atom_no – Number of atoms in cell valence – Valence of each atom in cell Volume – Volume of the cell Unit Surface Energy Error in eV/Ang^2
