First-principle investigation of boron nitride nanobelt

[Display omitted] •BN-nanobelt have exceptional stability.•The BN nanobelt absorbs in the UV region indicating a potential application as UV detector.•Quantum molecular dynamics showed that BN nanobelt presents high thermal stability. In this paper, we report a new boron nitride molecular structure called BN-nanobelt, an inorganic analog of (12) cyclophenacene synthesized in 2017. An extensive investigation using Density Functional Theory (DFT) and Quantum Molecular Dynamics (QMD) calculations showed that BN-nanobelt is a structurally and thermally stable molecule with all positive vibrational frequencies. BN-nanobelt behaves as an insulator, and it absorbs in the ultraviolet region, suggesting a potential application as a UV detector. All results presented in this paper indicate structural stability and the possibility of its synthesis. We hope that the proposed BN-nanobelt structure could stimulate further experimental investigations on its synthesis and bring potential novel technological applications.
