The electronic structure, effective mass, optical properties and electrical transport coefficients of APdCu(Se2)(Se3) (where A = K and Rb), a new quaternary copper palladium polyselenide, were investigated using a density functional theory calculation within a generalized gradient approximation (GGA) plus the Hubbard term (U) (GGA + U).

The Density Functional Theory

ABSTRACTUsing the density functional theory (DFT) and time dependent DFT, within the generalized gradient approximation (GGA), the electronic and optical properties of stoichiometric (ZnS)n nanoparticles (NP) were calculated. The dependence of the gap on the size (n) of the nanoparticle will be presented. The effect of replacing S atoms with P, Se or Te atoms in the (ZnS)n nanoparticles and its influence in the gap will be also shown.
