Electron interaction with point defects in CdSe0.35Te0.65: joining of ab initio approach with short-range principle

This study examines the problem of influence of point defects on transport phenomena in CdSexTe1-x (x=0.35) crystals. For the first time, the calculation of the electronic spectrum, wave function and potential energy of the electron in CdSe0.35Te0.65 samples at a prearranged   temperature was carried out. Using the supercell method, the types of point defects were established, as well as the temperature dependence of their ionization energies in the studied temperature range.

Transport phenomena in copper doped cadmium telluride: calculation from the first principles

In the presented work, the method of determining the energy spectrum, the wave function of the heavy hole and the crystal potential in CdTe at an arbitrarily given temperature is considered. Using this approach within the framework of the supercell method the temperature dependences of the ionization energies of various types of defects caused by the introduction of copper impurity in cadmium telluride are calculated.

The Quantum-Chemical and Spectral Criteria for Hydrogen Bonding Efficiency in Structural Analysis of Aramides

Some features of hydrogen bonding effects for the phenylon polymer matrix filled with a terlon fiber have been investigated at ab initio approximation. The results of calculations for isolated and dimerized structural forms of N-phenylbenzamide as a model compound are in good agreement with the spectral data for this composite material building.

The quantum-chemical modelling of structure and spectral characteristics for molecular complexes in pentaplast-terlon system

Using ab initio methods of quantum chemistry, structure and spectral properties of the molecular complexes which were formed by monomer of pentaplast chain and N-phenylbenzamide, that recreate features of intermolecular interaction in the penton-terlon system were researched.
