The structural stabilities and electronic structures of W atomic chains are studied by employing first-principles plane wave pseudopotential method based on the density functional theory.
The results reveal that it is viable to calculate the electron structure and phonon energy of lead using LDA and DFPT methods, and the calculated results are credible.
The optical properties and electrical structure of V in ZnS supercell have been computed by means of plane wave pseudo-potential method(PWP) with generalized gradient approximation(GGA).
