in the name of God
I am sorry for not explaining about my question, it is because of my
weakness in english,
I am working on cu(111) slab. I have 15 layer, and I want to optimize
my lattice constant. but I don`t know how to do it correctly.
I tried to change my lattice constant and calculate the total energy
and draw the diagram of lattice constant according to total energy but
the lattice constant which have the smallest total energy is so biger
that my experimental lattice constant.
so if any body knows how can I optimize my lattice constant please let me know.
thank you.
