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 …

Recently, several research groups have reported the growth of germanene, a new member
of the graphene family. Germanene is in many aspects very similar to graphene, but in …

Germanene, a 2D honeycomb structure similar to silicene, has been fabricated on Al (111).
The 2D germanene layer covers uniformly the substrate with a large coherence over the Al …

Abstract 2D materials have attracted considerable attention in the past decade for their
superlative physical properties. These materials consist of atomically thin sheets exhibiting …

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 …

By building physically sound interatomic force constants, we offer evidence of the universal
presence of a quadratic phonon branch in all unstrained 2D materials, thus contradicting …

Two-dimensional (2D) materials exhibit a wide range of atomic structures, compositions, and
associated versatility of properties. Furthermore, for a given composition, a variety of …
