  • Consider:
  1. a square simulation box whose sides are of length L
  2. a number of lattice positions, M given by M=m2 ; with m being a positive integer
  • The M positions are those given by:
{x=i×(δl);i=0,1,⋯,m−1y=j×(δl);j=0,1,⋯,m−1

where δl=L/m

Atomic position(s) on a square cell

  • Number of atoms per cell: 1
  • Coordinates:

Atom 1: (x1,y1)=(0,0)
