First-Principles Determination of the Soft Mode in Cubic ZrO 2

TL;DR: In this paper, a direct approach to calculate the phonon dispersion using an ab initio force constant method was introduced, where the authors derived the force constants from the Hellmann-Feynman forces induced by the displacement of an atom in the fcc supercell.
Journal ArticleDOI

Novel Electronic and Magnetic Properties of Two‐Dimensional Transition Metal Carbides and Nitrides

TL;DR: In this article, the formation and electronic properties of various MXene systems, M 2 C (M = Sc, Ti, V, Cr, Zr, Nb, Ta), M 2 N (M 2 N), with surfaces chemically functionalized by F, OH, and O groups, are examined.
Journal ArticleDOI

Penta-graphene: A new carbon allotrope

TL;DR: It is shown that penta-graphene, composed of only carbon pentagons and resembling Cairo pentagonal tiling, is dynamically, thermally, and mechanically stable, and exhibits negative Poisson's ratio, a large band gap, and an ultrahigh mechanical strength.
Journal ArticleDOI

Ferromagnetism in Semihydrogenated Graphene Sheet

TL;DR: Using density functional theory, it is shown that when half of the hydrogen in this graphane sheet is removed, the resulting semihydrogenated graphene becomes a ferromagnetic semiconductor with a small indirect gap.
