Freestanding silicene, a monolayer of Si arranged in a honeycomb structure, has been
predicted to give rise to massless Dirac fermions, akin to graphene. However, Si structures …

Silicene, a single layer of Si atoms, shares many remarkable electronic properties with
graphene. So far, silicene has been synthesized in its epitaxial form on a few surfaces of …

The discovery of (4× 4) silicene formation on Ag (111) raised the question whether silicene
maintains its Dirac fermion character, similar to graphene, on a supporting substrate …

Abstract Silicene, the two-dimensional (2D) allotrope of silicon, is a promising material for
electronics. So far, the most direct synthesis strategy has been to grow it epitaxially on metal …

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 distinct …

Silicene, the two-dimensional allotrope of silicon, is predicted to exist in a low-buckled
honeycomb lattice, characterized by semimetallic electronic bands with graphenelike energy …

The growth of the 3× 3 reconstructed silicene on Ag substrate has been frequently observed
in experiments while its atomic structure and formation mechanism is poorly understood …

Scanning tunneling microscopy has been used to real-time study the growth of silicene on
Ag (111) in the 200–533-K temperature range. We show that the growth mode depends …

In this study, the stability and electronic characteristics of epitaxial silicene bilayers and
multilayers on the Ag (111) surface are investigated through synchrotron‐based soft X‐ray …

Having fueled the microelectronics industry for over 50 years, silicon is arguably the most
studied and influential semiconductor. With the recent emergence of two-dimensional (2D) …
