The very concept if "k-point sampling" applies to periodic systems. Interfaces, by definition, break translational invariance. If you want to study them with periodic models (only choice with QE) you have to build such a model first, i.e. you have to define a suitable supercell. SB - SISSA

Would anyone please give me some suggestions?
