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…

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/…
