Here we choose to build upon the framework of density functional theory DFT which provides an efficient means to investigate a system from a quantum mechanics description. Zinc Phosphide Zn 3 P 2 could be the basis for cheap and highly efficient solar cells.
The density functional theory DFT treats the electron density as the central variable rather than the manybody wavefunction. This conceptual difference leads to a remarkable reduction in difficulty the density is a function of three variables. the three Cartesian directions,9, University at Albany,the ground state properties of a system. This also marked the birth of density functional theory DFT to which the main part of this thesis is devoted.
