A hierarchical research by large-scale and ab initio electronic structure theories -- Si and Ge cleavage and stepped (111)-2x1 surfaces --
Takeo Hoshi, Masakazu Tanikawa, Akira Ishii
The ab initio calculation with the density functional theory and plane-wave bases is carried out for stepped Si(111)-2x1 surfaces that were predicted in a cleavage simulation by th…
DFT calculation for adatom adsorption on graphene sheet as a prototype of carbon nano tube functionalization
Akira Ishii, Masana Yamamoto, Hiroki Asano +1
DFT calculation of various atomic species on graphene sheet is investigated as prototypes for formation of nano-structures on carbon nanotube (CNT) wall. We investigate computation…
Growth mechanisms of GaN on the O-terminated ZnO(000-1) surfaces
Katsutoshi Fujiwara, Akira Ishii, Toshikazu Ebisuzaki +4
We have investigated the stability of the 1ML-GaN on the O-polarity ZnO(000-1) interface structure using the first-principles calculation. We have found in our calculated results t…
The kinetic Monte Carlo Simulation scheme of the homoepicaxial growth of GaAs(001) for heterostructural growth on GaAs(001) substrate
Akira Ishii, Masatoshi Tsukao, Natsue Toda +1
The simulation scheme for heterostructural growth of compound semiconductors is presented based on the kinetic Monte Carlo method. The sheme is designed as simple as possible in or…
d-like Symmetry of the Order Parameter and Intrinsic Josephson Effects in Bi2212 Cross-Whisker Junctions
Yoshihiko Takano, Takeshi Hatano, Akihiro Fukuyo +5
An intrinsic tunnel junction was made using two Bi-2212 single crystal whiskers. The two whiskers with a cross-angle were overlaid at their c-planes and connected by annealing. The…
A Cross-Whiskers Junction as a Novel Fabrication Process for Intrinsic Josephson Junction
Yoshihiko Takano, Takeshi Hatano, Akihiro Fukuyo +4
A Bi2Sr2CaCu2O8+d cross-whiskers junction has been successfully discovered as a novel intrinsic Josephson junction without using any technique for micro-fabrication. Two Bi2Sr2CaCu…
