Room-temperature ferromagnetic CoSenanoplates synthesized by chemical vapor deposition.

Among novel two-dimensional materials, transition metal dichalcogenides (TMDs) with 3magnetic elements have been extensively researched owing to their unique magnetic, electric, and photoelectric properties. As an important member of TMDs, CoSeis an interesting material with controversial magnetic properties, hitherto there are few reports related to the magnetism of CoSematerials. Here, we report the synthesis of CoSenanoplates on AlOsubstrates by chemical vapor deposition (CVD).

Structural Determination of a Graphite/Hexagonal Boron Nitride Superlattice Observed in the Experiment.

A previous study reported an observed unidentified graphite/hexagonal boron nitride (hBN) superlattice structure in special multilayer heterojunction devices via cross-sectional transmission electron microscopy [Haigh S. J. .

Universal Phase Transitions of AlB-Type Transition-Metal Diborides.

High-pressure phase transitions of AlB-type transition-metal diborides (TMB; TM = Zr, Sc, Ti, Nb, and Y) were systematically investigated using first-principles calculations. Upon subjecting to pressure, these TMB compounds underwent universal phase transitions from an AlB-type to a new high-pressure phase tP6 structure. The analysis of the atomistic mechanism suggests that the tP6 phases result from atomic layer folds of the AlB-type parent phases under pressure.

Three metallic BN polymorphs: 1D multi-threaded conduction in a 3D network.

In this paper, three novel metallic sp2/sp3-hybridized boron nitride (BN) polymorphs are proposed by first-principles calculations. One of them, denoted as tP-BN, is predicted based on the evolutionary particle swarm structural search. tP-BN is composed of two interlocked rings forming a tube-like 3D network.
