To transform the study of this system with N particles in interaction at the study of a one particle in mean potential created by the N-1 other particles we use the variational principle.

Density of State Calculations for Tl3SbS3 and SbTeI

In the present work, we find for Lapw-kethods eI also an indirect gap [ 17 – 20 ] 1. Groups Connections Recommendations Neighbours Watchlist. The calculation is based on the local density approximation LDA for exchange correlation potential which permitted us to step-by-setp good densities of state for Tl3SbS3 and SbT eI.

Study their properties was necessary to find a technique based on numerical simulation. Phy Rev B The valence density of states VDOS curves exhibit three bands, with a characteristic three peak structure for the upper portion and core-like level for the lower band. Condens Matter Phys All these methods are based on a minimization of the total energy system. Register and you can start organising your references online.

B we present the main results of this calculation and we discuss it. J Non-Cryst Solids For each step we have compared, judged and verified the consistency of results found and the validity of our calculations by basing over all applied and theoretical works done by other methods [ 16 ].
