A new Green–function program for electronic–structure calculations for periodic crystals in shortly described and some modifications necessary for using the Intel iPSC/860 are given. The computing power of the iPSC/860 for the total–energy calculation of fcc Cu is compared to various other computers.

We present software on total energy calculation by quantum mechanics first principle method with a graphic user interface (GUI). Total energy calculation in this software is based on numerical analysis of time-dependent density functional (the used numerical method is finite difference time domain). QUMEC package has been equipped by common exchange-correlation energy terms with electron spin polarization calculation. With this package, users can calculate the total energy of the free particle, bulk materials, and materials with free surfaces at the atomic scale. The package is tested by several physical subjects, i.e., the surface energy of nano-LiCoO2 and diffusion constant of lithium atoms in LiNi­0.5Mn1.5O4.

A theoretical study of the electronic and optical properties of dilute magnetic semiconductor Sr3SnO is presented, using the full potential linearized augmented plane wave method. The Perdew Burke Ernzerhof (GGA08) (generalized gradient approximation) is used for the total energy calculations, while the Modified Becke–Johnson (MBJ) is used for electronic structure calculations since this functional was designed to reproduce as well as possible the exact exchange correlation potential rather than the total energy, and as a result gives significantly improved results such as band gap and electronic structure. In this study, we have investigated the optical properties by means of first-principles density-functional total-energy calculation using the all-electron full potential linear augmented plane-wave method (FPLAPW).

The electronic structure and elastic properties of the ternary layered carbide V3GeC2 were investigated by the first-principle plane-wave pseudopotential total energy calculation method based on density functional theory. It is found that the computed P63/mmc lattice constants and internal coordinates are a = 2.9636?, c = 17.2256? and zV2 = 0.1325, zC = 0.5712, respectively. The predictable cohesive energy of V3GeC2 reflects that it could be a stable Mn+1AXn phase like Ti3GeC2 and V2GeC, while the band structure shows that the V3GeC2 has anisotropic electrical conductivity, with a high density of states at the Fermi energy. The V3GeC2 exhibits potential anisotropic elastic properties, as well as self-lubricating and ductile behaviour, related to the V-Ge bonds being relatively weaker than the V-C bonds.
