Ni(NCS)₂ monolayer: a robust bipolar magnetic semiconductor

Abstract

Searching for experimentally feasible intrinsic two-dimensional ferromagnetic semiconductors is of great significance for applications of nanoscale spintronic devices. Here, based on the first-principles calculations, Ni(NCS)2 monolayer was systematically investigated. The...

Twist-stacked 2D bilayer Fe3GeTe2 with tunable magnetism

“…We conclude that the strong SOC induced by the Te ions and the contribution of Fe anions to the magnetization (with a small orbital moment of 0.08 m B per Fe) together, lead to a robust MAE of the FGT bilayer. 28,56,57…”

X-ray spectroscopy for the magnetic study of the van der Waals ferromagnet CrSiTe3 in the few- and monolayer limit

“…Semiconducting magnets, such as CrSiTe 3 (CST) [17][18][19] or monolayer Ni(NCS) 2 [20], are interesting members of the family of vdW magnets since in semiconductors, apart from their electronic properties, also the magnetism can be precisely tuned via electrical gating [21], making them ideal materials for spintronics applications. The magnetic properties of CST have been found to be strongly thickness dependent, which is common to all 2D magnets, however, with a rather unique increase (instead of the usual decrease) in the magnetic transition temperature as the films approach the monolayer limit [22,23].…”

Ultrahigh mechanical flexibility induced superior piezoelectricity of InSeBr-type 2D Janus materials

“…Nonetheless, the piezoelectric properties of 2D materials are still inferior to those of optimized 3D perovskite materials, which significantly restrict the practical applications of the 2D piezoelectric materials in micro-and nano-electronic devices. 28,30,[32][33][34] Thus, it is of importance that 2D materials with piezoelectricity compatible to that of 3D materials could be explored.…”
