Abstract
Successive over-relaxation method has been adopted to find the wave functions corresponding to the band states and surface states and also to solve energy dispersion relation for 2D finite crystal of desirable shape and size with periodic and non-periodic potentials. This method enables us to study the finite size effect in 2D crystals without costing too much computer time like ab initio methods. The major advantage of over-relaxation method is its simplicity as well as its usefulness in both lower and higher dimensional finite systems.
