We calculated the energy band structures of the double TI-O layer TI-Ba-Ca-CuO oxide superconductors by performing the tight-binding band structure calculation method on the basis of EHT approximation.
We calculated the energy band structures of YBa_2Cu_3O_(7-δ)andYBa_2Cu_3O_6 by performing the tight-binding band structure calculation methodon the basis of EHT approximation.
Based on a recent band structure calculation,the electron transport properties in Nitrogen-doped 4H-SiC were investigated by an ensemble Monte Carlo technique with a single nonparabolic band model.
By the electronic band structure calculation based on first-principles, we, for the first time, forecast a significant enhancement of electronic conductivity when lithium ions are replaced by cations with higher valence, Cr3+, and two kinds of possible conduction mechanisms are proposed. Thus, a variety of possible controversy and doubt is clarified.
The electronic structure calculation shows, the magnetic moments of Fe (4c), Fe (8ji) and Fe (16k2) are lowered, while the magnetic moments of Fe (4e) are increased.
The energy band structures of Bi-Sr-Ca-Ou-o superconductors were calculated by performing the tight-binding calculation method on the basis of EHT approximation.
The bands of metallic coordinated polymers[{HgX 2(bipy)} n]with layer skeleton (X=Cl,Br;bipy=4,4′ bipyridyl)have been calculated by the EHT crystal orbital method. The main bonding of energy bands has been discussed by the Band Vector Method.
The experimental anisotropies are in very satisfactory agreement with earlier measurements and there is good qualitative agreement between the experimental data and a recent band structure calculation.
Because of the variational character of the most of the modern band structure calculation methods, including LMTO, the calculated electron energies are much more accurate than the wave functions.
In this paper, a Scalar Eelativiatic Green's Function method ( SRA-KKR) neglecting spin-orbit coupling effect has been proposed for the energy band calculation. With this method, only a few modifications to the Non-Relativistic Green's Function method would be needed in order to obtain the relativiatic effect on the electronic band structure of solid.
Based on the distingush ed feature of the all-electron LMTO-ASA method, a LMTO ASA Virtual Crystal Approximation (VCA) method for calculating band structure of semiconductor alloy is suggested and applied to the Ga1. xA1xAs system. It is found that the compositional dependence of band structure, density of states and bowing parameter clearly shows the basic feature of the VCA. The sum of valence electronic energies in alloy and the valency charge contained in the ASA spheres are found to be linearly depende...
