For the development of next-generation electronics, optoelectronics, and nanotechnology

Nickel phosphorus trisulfide (NiPS₃) is a layered quasi-two dimensional antiferromagnetic (AFM) semiconductor (T_N=155 K). Nickel phosphorus trisulfide (NiPS₃) belongs to the group of 2D layered transition metal phosphorus trichalcogenides (MPX₃). Among them, NiPS₃ has quite unique physical properties with capability of both p-type and n-type doping for device applications and the smallest bandgap energy (~1.6 eV).

Applications

Development of next-generation electronics, optoelectronics, and nanotechnology

The antiferromagnetic ordering in NiPS₃ is persistent down to two-layer nano-structures and is substantially suppressed in the monolayer, unlike the case of Ising-type antiferromagnet FePS₃ in which antiferromagnetic ordering maintains down to the monolayer limit. Antiferromagnetic van der Waals material NiPS₃ offers a good model system for the XY Hamiltonian or XXZ-type, while FePS₃ of anistropic Ising-type and MnPS₃ of isotropic Heisenberg-type.

Structure of Nickel Phosphorus Trisulfide

NiPS₃ crystalises in monoclinic crystal structure containing two molecular formula units per unit cell (Ni₂P₂S₆). NiPS₃ consists of layers of covalently bonded clusters of [P₂Se₆]⁴^-dumbbell bipyramids with honeycomb arrangement of divalent nickel ions. Individual layers are bound via weak van der Waals and can be easily separated into few-layer nanosheets by either mechanical or liquid exfoliation.

Transition metal phosphorus trichalcogenides (MPX₃)
NiPS₃ offers a good model system for the XY Hamiltonian or XXZ-type
NiPS₃ is a layered quasi-two dimensional antiferromagnetic semiconductor (T_N=155 K)
The antiferromagnetic ordering in NiPS₃ is persistent down to bilayer and substantially suppressed in the monolayer,

Applications of Nicklel Phosphorus Trisulfide

Nickel phosphorus trisulfide (NiPS₃) single crystals can be used to prepare monolayer and few-layer NiPS₃ by mechanical or liquid exfoliation.

Nickel phosphorus trisulfide is suitable for liquid chemical exfoliation to prepare NiPS₃ nanosheets and nanoparticles down to few-layer films.

Nickel phosphorus trisulfide exhibits n-type semiconducting behaviour with on/off ratio of 10³–10⁵. NiPS₃ nanosheets can be built into humidity sensors, FETs, modulators, switches and health and environmental monitoring devices.

Ultrathin few-layer nickel phosphorus trisulfide nanosheets has great potentials as anodes for lithium ion batteries (LIBs) with excellent electrochemical properties in terms of stable cycling performance and rate capabilities

With appropriate positions of the band edges, NiPS₃ can directly generate hydrogen gas from pure water without any sacrificial agents under sunlight. NiPS₃ nanosheets is also being explored as electrocatalysts for oxygen evolution reaction (OER) with outstanding long-term durability.

Viscoelastic Transfer of 2D Material Using PDMS

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. It relies on the viscoelasticity of PDMS, which behaves as an elastic solid on short time scales, but as a viscous fluid on long time scales.
