Magnetoelectronic properties of normal and skewed phosphorene nanoribbons
The energy spectrum and eigenstates of single-layer black phosphorous nanoribbons in the presence of perpendicular magnetic field and in-plane transverse electric field are investigated by means of a tight-binding method and the effect of different types of edges is analytically examined. A description based on a new continuous model is proposed by expansion of the tight-binding model in the lo...
متن کاملZigzag phosphorene nanoribbons: one-dimensional resonant channels in two-dimensional atomic crystals
We theoretically investigate phosphorene zigzag nanoribbons as a platform for constriction engineering. In the presence of a constriction at one of the edges, quantum confinement of edge-protected states reveals conductance peaks, if the edge is uncoupled from the other edge. If the constriction is narrow enough to promote coupling between edges, it gives rise to Fano-like resonances as well as...
متن کاملUnexpected Magnetic Semiconductor Behavior in Zigzag Phosphorene Nanoribbons Driven by Half-Filled One Dimensional Band
Phosphorene, as a novel two-dimensional material, has attracted a great interest due to its novel electronic structure. The pursuit of controlled magnetism in Phosphorene in particular has been persisting goal in this area. In this paper, an antiferromagnetic insulating state has been found in the zigzag phosphorene nanoribbons (ZPNRs) from the comprehensive density functional theory calculatio...
متن کاملψ-Phosphorene: a new allotrope of phosphorene.
Based on the crystal structure prediction, we propose a new allotrope of phosphorene, ψ-phosphorene (ψ-P), with a porous structure, which is both thermally and dynamically stable in comparison with the previously reported allotropes. Due to its unique atom configuration, ψ-P has highly orientation-dependent mechanical properties and excellent flexibility. Calculations using the HSE functional p...
متن کاملTiling phosphorene.
We present a scheme to categorize the structure of different layered phosphorene allotropes by mapping their nonplanar atomic structure onto a two-color 2D triangular tiling pattern. In the buckled structure of a phosphorene monolayer, we assign atoms in "top" positions to dark tiles and atoms in "bottom" positions to light tiles. Optimum sp3 bonding is maintained throughout the structure when ...
