Abstract We employ a four-band continuum model to study the transport and confinement in an n-p-n junction bilayer chiral borophene for both identical- opposite-chirality configurations. demonstrate existence of topological states domain wall between domains with reversed layer stacking. An interlayer bias modifies conductance identical-chirality configuration but not that configuration, it ind...

Two-dimensional (2D) atomically thin boron layers designated as borophene or boraphene, attract great interest promising post-graphene 2D materials. The layer phonon structure has not yet been clarified by experimentation in spite of its importance for application possible superconduction and thermal technologies. For this work we measured, experimentation, the dispersion an incommensurate thre...

Various types of zero, one, and two-dimensional boron nanomaterials such as nanoclusters, nanowires, nanotubes, nanobelts, nanoribbons, nanosheets, and monolayer crystalline sheets named borophene have been experimentally synthesized and identified in the last 20 years. Owing to their low dimensionality, boron nanomaterials have different bonding configurations from those of three-dimensional b...

Very recently, borophene (atomic-thin two-dimensional boron sheet) has been successfully synthesized on the Ag(111) surface by deposition. Two kinds of structures were found. However, the identification of the monolayer boron sheets grown on the metal substrate, as well as the stability of different 2D boron sheets, is controversial. By performing the first-principles calculations, present stud...

Density functional theory calculations are robust tools to explore the mechanical properties of pristine structures at their ground state but become exceedingly expensive for large systems finite temperatures. Classical molecular dynamics (CMD) simulations offer possibility study larger elevated temperatures, they require accurate interatomic potentials. Herein authors propose concept first-pri...

Over the past years, two-dimensional materials such as graphene, phosphorene, silicene, and boron-nitride have attracted the attention of many researchers. After the successful synthesis of graphene, due to its many new applications, researches began to produce nanosheets from other elements, and among these elements, boron was one of the options. In the periodic table of elements, boron is ahe...
