Silicene, a silicon analogue of graphene, has attracted increasing attention during the past
few years. As early as in 1994, the possibility of stage corrugation in the Si analogs of …

Two-dimensional (2D) materials are characterised by their strong intraplanar bonding but
weak interplanar interaction. Interfaces between neighboring 2D layers or between 2D …

We report the recent progress on the theoretical aspects of monolayer topological insulators
including silicene, germanene and stanene, which are monolayer honeycomb structures of …

Inspired by the great development of graphene, more and more research has been
conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D Dirac …

Monolayer germanene, a novel graphene-like germanium allotrope akin to silicene has
been recently grown on metallic substrates. Lying directly on the metal surfaces the …

Silicene is emerging as a two-dimensional material with very attractive electronic properties
for a wide range of applications; it is a particularly promising material for nano-electronics in …

Breakthrough of graphene dictates that decreasing dimensionality of the semiconducting
materials can generate unusual electronic structures, excellent mechanical, and thermal …

Strategies capable of inducing multifunctionality in materials in a controllable manner are
highly desirable. In this work, we have brought multifunctionality to a two-dimensional (2D) …

Since the breakthrough of graphene, considerable efforts have been made to search for two-
dimensional (2D) materials composed of other group 14 elements, in particular silicon and …

Silicene is a two-dimensional allotrope of silicon with a puckered hexagonal structure
closely related to the structure of graphene and that has been predicted to be stable. To …
