#Definition of the atom types
ntypat 1 # There is only one type of atom
znucl 6 # The keyword "znucl" refers to the atomic number of the
# possible type(s) of atom. The pseudopotential(s)

# to the type(s) of atom. Here, the only type is Silicon.
#Definition of the atoms
natom 2 # There are two atoms
