Abstract Since penta-graphene (PG), a two-dimensional (2D) carbon allotrope exclusively
composed of five-membered rings, was proposed in 2015, a great deal of effort has been …

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 most direct and efficient strategy in designing and synthesizing new materials is to
change the structural building units, which could lead to a new paradigm shift. Penta …

Materials and their interfaces are the core for the development of a large variety of fields,
including catalysis, energy storage and conversion. In this case, tip-enhanced Raman …

As the" fingerprint" spectrum of substances, surface-enhanced Raman scattering (SERS)
has extremely high sensitivity. It can detect the molecular traits on the metal surface and …

Silicon is one of the most frequently used chemical elements of the periodic table in
nanotechnology (Goodilin et al., ACS Nano 2019, 13, 10879–10886). Two-dimensional …

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 …

The successful fabrication of a two-dimensional boron sheet, which features a triangular
lattice with periodic hole arrays, has stimulated great interest in its specific structure as well …

In the realm of two-dimensional (2D) materials, besides the ones initially peeled from
lamellar crystals, the artificial emerging elemental ones, called Xenes, appear as strong …

Silicon surface alloys and silicide nanolayers are highly important as contact materials in
integrated circuit devices. Here we demonstrate that the submonolayer Si/Ag (001) surface …
