Hexagonal Boron Nitride (hBN) is a layered material with a structure analogous to that of graphene. Within each layer, it is composed of alternating boron and nitrogen atoms that are arranged in a sp 2 bonded network. The bond length between boron and nitrogen is 1.44 A°, whereas the bond length between carbon atoms in graphene is …

Boron-doped graphene is envisioned as a highly promising anode material for alkali metal-ion batteries (MIBs). However, due to the large structural space concerning various doping concentrations, the lack of both datasets and effective methods hinders the discovery of boron-doped graphene with a high WF that generally leads to strong …

Borophene is based upon boron just as graphene is based upon carbon. This is significant because at nano level, small atomic clusters of carbon and boron are quite astonishingly similar, even though their macroscopic-level allotropes are quite different. Thus the presence of a 2D boron substance like graphene was predicted theoretically …

A carbon/boron compound in which a quarter of the carbon atoms are replaced by boron turned out to be nearly ideal as a way to activate graphene's ability to store lithium, Yakobson said. Boron attracts lithium ions into the matrix, but not so strongly that they can't be pulled away from a carbon/boron anode by a more attractive cathode.

The unit cell of graphene's lattice consists of two di erent types of sites, which we will call Asites and Bsites (see Fig. 1). Figure 1: Honeycomb lattice and its Brillouin zone.

Abstract. Carbon and boron can mix to form numerous two-dimensional (2D) compounds with strong covalent bonds, yet very few possess a bandgap for functional applications. Motivated by the structural similarity between graphene and recently synthesized borophene, we propose a new family of semiconducting boron carbide monolayers …
