Structural Evolution and Optoelectronic Applications of Multilayer Silicene
Zhi-Xin Guo, Yue-Yu Zhang, Hongjun Xiang +2
Despite the recent progress on two-dimensional multilayer materials (2DMM) with weak interlayer interactions, the investigation on 2DMM with strong interlayer interactions is far f…
Structural stability and energy-gap modulation through atomic protrusion in freestanding bilayer silicene
Yuki Sakai, Atsushi Oshiyama
We report on first-principles total-energy and phonon calculations that clarify structural stability and electronic properties of freestanding bilayer silicene. By extensive struct…
Crossover between Silicene and Ultra-Thin Si Atomic Layers on Ag(111) Surfaces
Zhi-Xin Guo, Atsushi Oshiyama
We report on total-energy electronic structure calculations in the density-functional theory performed for the ultra-thin atomic layers of Si on Ag(111) surfaces. We find several d…
Structural Tristability and Deep Dirac States in Bilayer Silicene on Ag(111) Surfaces
Zhi-Xin Guo, Atsushi Oshiyama
We report on total-energy electronic-structure calculations in the density-functional theory performed for both monolayer and bilayer silicene on Ag(111) surfaces. The rt3 x rt3 st…
New Identification of Metallic Phases of In Atomic layers on Si(111) Surfaces
Kazuyuki Uchida, Atsushi Oshiyama
We report first-principles calculations that clarify atomic structures and coverage of the metallic phases of In overlayers on Si (111) surfaces. Calculated energy bands and scanni…
Absence of Dirac Electrons in Silicene on Ag (111) Surfaces
Zhi-Xin Guo, Shinnosuke Furuya, Jun-ichi Iwata +1
We report first-principles calculations that clarify stability and electronic structures of silicene on Ag(111) surfaces. We find that several stable structures exist for silicene/…
