We revealed a mechanism of hole doping into hydrogen (H) terminated diamond by the adsorption of inorganic molecules, based on first-principle calculation. Electron transfer from H-terminated diamond to adsorbate molecules was found in the case that

Based on a first-principles total-energy calculation, we demonstrate the possibility of π electron network design in graphene using atomic Pt adsorbate. The d state of the adsorbed Pt atoms hybridizes with the π state of graphene, which effectively

We report a numerical investigation on the catalytic growth mechanism of a single-walled carbon nanotube (SWNT) inside a template SWNT, that is, formation of a double-walled carbon nanotube (DWNT). The molecular dynamics simulations together with com

First-principle electronic structure calculation reveals the appearance of a new class of surface state on hydrogenated and clean Si(1 1 1) surfaces. The states are found to exhibit different characteristics to conventional surface electron states in

Magnetism of nanographite is examined by consideration based on known rigorous theorems for the Hubbard model. For a bearded nanographite ribbon with the zigzag edge on one side and Klein's decorated edge on the other side, the surface magnetization

We have shown a theoretical method to construct structures called “hyper-graphite” which can be regarded as a generalization of the graphite structure. Based on the method, we propose a possible 3-dimensional network, which may be realized as a
