Prof Nicola, Thank you! Thank you very much!!! And thanks a lot for Dr.Claudia Bungaro's PhD paper. Now I kown how to insert the bulk constants in to the slab. One more question, I want to calculate the el-ph interaction of a metal surface next step. If I use a normal method in pwscf, I will get interaction between all phonons(surface+resonance+bulk) and all electrons(surface+resonance+bulk).If I want to analyse the el-ph interaction at surface, should I selected the surface phonons and surface electrons out? Does it means that I should modify the pwscf source files? May I specify the phonon mode of some special q point, then calculate the lamda(q,v) with the surface electrons? Are there any articles about these? Thanks Best regards
