ψ-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 ...
متن کاملThreshold Determination and Engaging Materials Scientists in Ontology Design
This paper reports on research exploring a threshold for engaging scientists in semantic ontology development. The domain application, nanocrystalline metals, was pursued using a multi-method approach involving algorithm comparison, semantic concept/term evaluation, and term sorting. Algorithms from four open source term extraction applications (RAKE, Tagger, Kea, and Maui) were applied to a te...
متن کاملInformal Phosphorene Symposium
Black phosphorous (BP) is is recently unveiled as a promising two-dimensional direct bandgap semiconducting material. Here, we report the ambipolar field effect transistor behavior of multilayers of BP with ferromagnetic tunnel contacts. We observe a reduced of Schottky barrier < 50 meV by using TiO2/Co contacts, which could be further tuned by gate voltages. Eminently a good transistor perform...
متن کاملOxygen defects in phosphorene.
Surface reactions with oxygen are a fundamental cause of the degradation of phosphorene. Using first-principles calculations, we show that for each oxygen atom adsorbed onto phosphorene there is an energy release of about 2 eV. Although the most stable oxygen adsorbed forms are electrically inactive and lead only to minor distortions of the lattice, there are low energy metastable forms which i...
