Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, appear
very promising due to their outstanding electronic properties, such as the quantum spin Hall …

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 …

Germanene, as an artificial graphene-like near room temperature topological insulator,
compatible with ubiquitous silicon technology, is potentially the most promising artificial …

In the last decade, research on 2D materials has expanded massively due to the popularity
of graphene. Although the chemical engineering of two-dimensional elemental materials as …

Several studies have reported the possible growth of germanene on various metal surfaces.
However, the exact structure of the layers formed upon evaporation at or above room …

The great moment of fame for germanium was in December 1947. In that year the first
transistor was made by a research team of Bell Laboratories. Owing to some problems with …

While the growth of germanene has been extensively claimed on many substrates, their
exact crystal structures remain controversial. Herein, we systematically explore the surface …

Determining surface structures is a substantial challenge due to the limitations of
experimental techniques and the complexity of theoretical models. In this work, we use a …

Two-dimensional sheets of ultra-thin germanium with the lattice parameter of free-standing
germanene, ie, 0.41 nm, are formed by atomic segregation epitaxy on face-centered-cubic …

The electronic structure and optical properties of bilayer germanene under different
warpages are studied by the first-principles method of density functional theory. The effects …
