With cutting-edge materials and minute electronic devices being produced by the latest nanoscale fabrication technology, it is essential for scientists and engineers to rely on first-principles (ab initio) calculation methods to fully understand the

On the basis of density functional theory, we study the electronic structures of five types of carbon nanotubes: the non-deformed (6,6) tube, the uniformly stretched tube along the tube axis, the uniformly compressed tube, the partially stretched tub

We have investigated electronic structures of the peanut-shaped polymerized fullerene with so-called P55, P56 and P66 tubular linkage structures. The stable atomic configurations in these one-dimensional or two-dimensionally bundled tubes are searche

We present theoretical study on the electronic structures of the interfaces between Si substrate and SiO2 under zero bias and when a bias of −1.0 V is applied to the substrate by the first-principle calculation based on real-space finite-difference

A tractable calculation algorithm to calculate essentially exact electron–electron correlation energies of few-electron systems by the superposition of nonorthogonal Slater determinants (SDs) is presented. The key to the proposed procedure for upda

The self-energy term used in transport calculations, which describes the coupling between electrode and transition regions, is able to be evaluated only from a limited number of the propagating and evanescent waves of a bulk electrode. This obviously

Electron-electron correlations in two-dimensional square-well quantum dots are investigated using the direct energy minimization scheme. Searches for groundstate charges and spin configurations are performed with varying the sizes of dots and the num
