Density of State Calculations for Tl3SbS3 and SbTeI

Export in format suitable for direct import into delicious. A Andriesh AM Properties of chalcogenide glasses for optical waveguides. E i is the eigenstate. Find this article at Save current location: Ozbay ME Ferroelectrics Even in situations where the two-body elementary interactions are well-known such as in atoms or molecules, or ajd clusters, it is not possible to solve exactly the many body Hamiltonian and it is necessary to use sophisticated many-body techniques to nd approximate solutions.


You may hide this message. The calculation is based on the local density approximation LDA for exchange correlation potential which permitted us to obtain good densities of state for Tl3SbS3 and SbT eI. Setup a permanent sync to delicious.

Density of State Calculations for Tl3SbS3 and SbTeI

The quantum state of the system is no only described by the wave function but by the electronic density. Guidelines Upcoming Special Issues. Study their properties was necessary to find a technique based on numerical simulation.

Familly electronic structure calculations of the SbT eI are available in the literature [ 17 – 20 ].

In annd present work, we find for SbT eI also an indirect gap [ 17 – 20 ] 1. People studying for PhDs or in postdoctoral postdoc positions.

The lowest band D, with a bandwidth of 0. Among these techniques we find the ab-initio, empirical and the semi empirical methods that became today a tool for step-bystep most complex electronic and structural property count.

The Table 1 give the value of predicted and calculated energy gap compared with experimental ones in eV [ 17 – 19 ]. Recently, it has become possible to compute with a great accuracy an important number of electronic structure materials from rst-principal calculations.

We have calculated the band structure and the total density of states by using the DFT theory; we remark the following main results: These methods do a rigorous resolution of the standard Schrodinger equation SE while calculating all integral of recovery the integral will be evaluated rigorously and all electrons are, in principle, taken steo-by-step account [ 1011 ].

We have calculated the band structure and the total density of states by using the DFT theory; we remark the following main results:. Related Products We introcuction identified the following relevant lab reagents.
