Comment on A Dirac-semimetal two-dimensional BeN4: Thickness-dependent electronic and optical properties [Appl. Phys. Lett. 118, 203103 (2021)]
arXiv:2109.00770
Abstract
Most recently, Bykov and coworkers reported the successful synthesis of layered structure of BeN4. Followed by the experimental report, Bafekry and coworkers published their first-principles results on the stability, electronic, optical and elastic constants of BeN4 monolayer. In the aforementioned work, authors made numerous wrong claims and reported erroneous results.
