Semi-infinite surfaces for adsorption: a valid approach?

I'm currently trying to surface reaction of small molecules on metal oxides in VASP. Several papers I've read have approached surface energy calculations in a variety of ways. … Any paper recommendations welcome to, I found the Fiorentini and Methfessel paper in a discussion on the VASP forum. Fiorentini, V., & Methfessel, M. (1996). …
