[QE-users] Binding energy for Graphene-metal interface

[wallexact at yahoo.com]

Hello All,
I started using QE this month and I'm interested in calculating the binding energy of graphene/cu(111) interface using just 1x1 unit cell of both.
I used vesta to create the cu(111) slab and also join the graphene with the cu(111) slab. I have an input file but I'm not certain if I got all the inputs correctly. Also, do I execute a 'vc-relax' or 'relax' calculation?
Your advice would be highly appreciated.
Thanks,
