The isolation of graphene in 2004 from graphite was a defining moment for the “birth” of a
field: two-dimensional (2D) materials. In recent years, there has been a rapidly increasing …

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 …

Free-standing silicene, a silicon analogue of graphene, has a buckled honeycomb lattice
and, because of its Dirac bandstructure, combined with its sensitive surface, offers the …

Silicene, the ultimate scaling of a silicon atomic sheet in a buckled honeycomb lattice,
represents a monoelemental class of two-dimensional (2D) materials similar to graphene …

The discovery of graphene and other two-dimensional (2D) materials together with recent
advances in exfoliation techniques have set the foundations for the manufacturing of single …

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 …

Two-dimensional (2D) materials with planar hypercoordinate motifs are extremely rare due
to the difficulty in stabilizing the planar hypercoordinate configurations in extended systems …

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 …

The discovery of graphene and its remarkable and exotic properties have aroused interest in
other elements and molecules that form 2D atomic layers, such as metal chalcogenides …
