Dear users I have read in some papers that investigate adsorption of some molecules in the gas phase
on the solid surface, the authors use only gamma point for the supercell of the catalyst (for example for 3*3*3 supercells). But in another ones, I see that they use some k-point even for supercells. This subject confuse me. Is there any rule for this? Any help will be appreciated. Regards David Foster Ph.D. Student of Chemistry
