Comment on “A novel two-dimensional boron-carbon-nitride (BCN) monolayer: A first-principles insight” [J. Appl. Phys. 130, 114301 (2021)]

Recently, Bafekry et al. [J. Appl. Phys. 130, 114301(2021)] reported their density functional theory results on the structural, phonon dispersion, elastic constants, and electronic properties of a BCN monolayer. The aforementioned theoretical work, however, includes erroneous results and discussions, as will be explained in this Comment.
