### CiteULike: Density Functional Theory and the family of (L)APW-methods: a step-by-step introduction

Read about how we use cookies. This development in computer simulations has opened up many interesting and existing possibilities in materials sciences. In the following section; we expose the method of calculations based on the theory of functional density, and in sec.

By writing the hamiltonian of Eq. These calculations are based mainly on the use of many approximations such as the local density approximation LDAthe approximation of generalized conjugate gradient GGA [ 6 ]. CiteULike is a free online bibliography manager. Solid State Commun The most common example is the system: Referring to the theorems of Hohenberg-Kohn HK [ 6 ], which present the most elementary theorems for this system of particles. J Alloys Compd For summary the Table 2 gives positions in eV of di erent peaks deducted by calculation of the density of states of and SbT eI.

In this context, we have used the Wien2k package [ 12 – 14 ] based on the local density approximation LDA. Select your language of interest to view the total content in your interested language. CiteULike organises scholarly or academic papers or literature and provides bibliographic which means it makes bibliographies for universities and higher education establishments.

Condens Matter Phys Their densities of states curves bring out characteristic features in the valence band a core like peak, at environ SbT eI is an interesting compound for the antimony chalcogenide family. In the present work, we find for SbT eI also an indirect gap [ 17 – 20 ] 1. Search all the public and authenticated articles in CiteULike.
