Product M2211A10 is a small bulk crystal of nickel phosphorus trisulfide (NiPS3), with a typical representative area of ≥10 mm2 and a purity of ≥99.999%. Grown synthetically by chemical vapor transport (CVT), this green, monoclinic material is a layered quasi-two-dimensional antiferromagnetic semiconductor with a Néel temperature of 155 K and a bulk bandgap of about 1.6 eV, the smallest in the MPX3 family of transition metal phosphorus trichalcogenides.
Its layers are held together only by weak van der Waals forces, so the crystal serves mainly as a source for single- or few-layer sheets made by mechanical or liquid exfoliation. These crystals and the films derived from them suit examination by atomic force microscopy or transmission electron microscopy.
NiPS3 can be doped both p-type and n-type. Its antiferromagnetic order survives down to the bilayer but is strongly suppressed in the monolayer, making it a useful model system for the XY or XXZ-type Hamiltonian in studies of 2D magnetism. Actual crystal areas and dimensions may vary.
- Preparing monolayer and few-layer NiPS3 sheets by mechanical or liquid exfoliation.
- Research on 2D magnetism and van der Waals antiferromagnets as an XY or XXZ-type model system.
- Fabricating n-type semiconducting devices such as FETs, modulators, switches and humidity sensors from NiPS3 nanosheets.
- Exploring few-layer nanosheets as anodes for lithium ion batteries.
- Studying solar hydrogen generation from pure water and electrocatalysis of the oxygen evolution reaction.
- Characterising crystals and exfoliated films by atomic force microscopy or transmission electron microscopy.
