Comment on "Semiconducting Layered Blue Phosphorus: A Computational Study"

TL;DR

This paper comments on a previous computational study of blue phosphorus, discussing its structure and van der Waals interactions, highlighting overlooked aspects in the original research.

Contribution

It provides critical insights into the structural elements and interlayer forces of blue phosphorus that were not addressed in the original study.

Findings

Questions the structural assumptions of blue phosphorus

Highlights the importance of van der Waals forces in layered blue phosphorus

Provides clarifications on the stability and electronic properties of blue phosphorus

Abstract

\noindent Using results drawn from the pages of PRL\cite{Zhu2014}, the authors comment on \textquotedblleft Semiconducting Layered Blue Phosphorus: A Computational Study\textquotedblright. In recent letter\cite{Zhu2014} unknown phase of phosphorus with high stability and a wide fundamental gap was proposed by Zhu, and Tom\'anek. The first half of the comment questioned elements of phosphorus blue structure, while the second half devoted to van der Waals forces between AB stacked blue phosphorus layers which missed by them.
