Mechanisms of initial oxidation of 4H-SiC (0001) and (000) surfaces unraveled by first-principles calculations
Yu-ichiro Matsushita, Atsushi Oshiyama
We have performed electronic state calculations to clarify the initial stage of the oxidation of the Si- and C-faces in 4H-SiC based on the density-functional theory. We investigat…
First-principles calculations that clarify energetics and reactions of oxygen adsorption and carbon desorption on 4H-SiC () surface
Han Li, Yu-ichiro Matsushita, Mauro Boero +1
We report static and dynamic first-principles calculations that provide atomistic pictures of the initial stage of the oxidation processes occurring at the () surface of…
Band-unfolding approach to Moirè-induced band-gap opening and Fermi-level-velocity reduction in twisted bilayer graphene
Hirofumi Nishi, Yu-ichiro Matsushita, Atsushi Oshiyama
We report on the energy spectrum of electrons in twisted bilayer graphene (tBLG) obtained by the band-unfolding method in the tight-binding model. We find the band-gap opening at p…
