Exploring the Linear Optical Properties of Borazine (B3N3) Doped Graphenes. 0D Flakes vs 2D Sheets

Hybrid graphene/(hexagonal-boron-nitride) systems start to play a pivotal role in the realm of two-dimensional materials for atomically thin two-dimensional integrated circuits. As a result, there is significant interest in fabricating BnNn-substituted graphene networks from the bottom-to-up to be used to as precursors in flexible two-dimensional one-atom thick electronic and optical devices. In this report, we present a piece of theoretical work dealing with the microscopic electronic dipole–dipole polarizabilities (static and dynamic) of borazine (B3N3) doped graphenes in zero and two dimensions. Polarizability is a fundamental property that describes the distortion of the electron cloud in the presence of weak static external electric fields and delivers important information about the electronic structure and spectroscopic behavior of molecules. The robust polarizability trends presented and discussed in this work point out local cyclic electron delocalization (aromaticity in rings) as the leading ele...
