Conspectus Boron is an interesting element with unusual polymorphism. While three-
dimensional (3D) structural motifs are prevalent in bulk boron, atomic boron clusters are …

The mechanical exfoliation of graphene from graphite provides the cornerstone for the
synthesis of other 2D materials with layered bulk structures, such as hexagonal boron …

Abstract Two‐dimensional (2D) materials, such as graphene and boron nitride, have specific
lattice structures independent of external conditions. In contrast, the structure of 2D boron …

Boron, a nearest-neighbor of carbon, is possibly the second element that can possess free-
standing flat monolayer structures, evidenced by recent successful synthesis of single …

The mechanical properties of 2D boron—borophene—are studied by first‐principles
calculations. The recently synthesized borophene with a 1/6 concentration of hollow …

The structural stability and diversity of elemental boron layers are evaluated by treating them
as pseudoalloy B1–x⬡ x, where⬡ is a vacancy in the close-packed triangular B lattice. This …

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 …

Boron synthesis, in theory: Although two-dimensional boron sheets have attracted
considerable interest because of their theoretically predicted properties, synthesis of such …

Chirality plays an important role in chemistry, biology, and materials science. The recent
discovery of the B40–/0 borospherenes marks the onset of a class of boron-based …

Two-dimensional (2D) materials tend to be mechanically flexible yet planar, especially when
adhered on metal substrates. Here, we show by first-principles calculations that periodic …
