Penta-BxNy sheet: a density functional theory study of two-dimensional material.
TL;DR: Detailed investigations of two-dimensional BxNy nanomaterials in the Cairo pentagonal tiling geometry fully composed of pentagons suggest penta-BN2 as an attractive material to call for further studies on both theory and experiment.
New carbon allotropes with metallic conducting properties: a first-principles prediction
Xinyu Fan,Jiao Li,Gang Chen +2 more
TL;DR: In this paper, the authors combine density functional theory and the global minimum structural search to find new α-, β-, and δ-phographene carbon allotropes, which are almost degenerate in energy with the previously reported phagraphene.
Half-metallicity and ferromagnetism in penta-AlN2 nanostructure.
TL;DR: A detailed first-principles study of the penta-AlN2 nanostructure in the Cairo pentagonal tiling geometry, which is dynamically stable due to the absence of imaginary mode in the calculated phonon spectrum, and is found to be a ferromagnetic semiconductor.

Silicene nanomeshes: bandgap opening by bond symmetry breaking and uniaxial strain
TL;DR: Based on the first-principles calculations, the mechanism of bandgap opening induced by the sublattice equivalence breaking through breaking the bond symmetry could split the π-like bands in the inversion symmetry preserved silicene nanomeshes, resulting into the ρa1 − πa2 and πz1 − πz2 band sets with sizable energy intervals.
Dirac cone move and bandgap on/off switching of graphene superlattice
Tian Tian Jia,Meng Meng Zheng,Xinyu Fan,Yan Su,Shu-Juan Li,Haiying Liu,Gang Chen,Yoshiyuki Kawazoe +7 more
TL;DR: A reversible switch between the high velocity properties of massless Fermions attributed to the linear dispersion relation around Dirac cone and the high on/off ratio properties associated with the sizable bandgap is suggested.
