Low price, high purity iron phosphorus trisulfide powder and crystals

Suitable for the creation of monolayer and few-layer films, nanosheets and nanoparticle magnetic graphene

Iron phosphorus trisulfide (FePS₃) belongs to the family of transition metal phosphorus trichalcogenides (MPX₃). FePS₃ contains Fe, S and P which are all earth abundant elements. In its bulk form, FePS₃is a layer structured antiferromagnetic semiconductor and can be exfoliated into few-layer 2D nanosheets. It is commonly referred to as 'magnetic graphene'.

FePS₃ is a good example of a low-temperature 2D antiferromagnetic insulator that can be tuned with pressure into an exotic metallic state. Under compression, the layered structure simultaneously undergoes large in-plane lattice collapses, abrupt spin-crossovers and insulator-metal transitions. Raman spectroscopy reveals that FePS₃ exhibits an Ising-type antiferromagnetic ordering down to the monolayer limit, suggesting that intra-layer spin interaction dominates the magnetic structure of FePS₃.

We supply low price iron phosphorus trisulfide - or magnetic graphene - powder and crystals.

Iron phosphorus trisulfide crystal

Structure of Iron Phosphorus Trisulfide

FePS₃ is a cation-ordered CdCl₂ type low-dimensional layered magnetic semiconductor. FePS₃ crystal has a monoclinic structure with the factor group C_2h. In each unit cell, the magnetic Fe atoms are octahedrally coordinated to six S atoms with a small trigonal distortion. The P atom is coordinated to three S atoms and one P atom to form a [P₂S₆]^4- unit. The [P₂S₆]^4- units are connected with six Fe atoms, which are arranged in a honeycomb plane structure.

Properties of Iron Phosphorus Trisulfide

After exfoliation of iron phosphorus trisulfide crystal or powder, FePS₃ typically has the following properties:

Monoclinic (space group: C2/m)
Transition metal phosphorus trichalcogenides (MPX₃)
Antiferromagnetic semiconductor with Ising-type antiferromagnetic ordering down to the monolayer limit
Insulator-metal transitions under compression

Applications of Iron Phosphorus Trisulfide

Iron phosphorus trisulfide (FePS₃) single crystals can be used to prepare monolayer and few-layer FePS₃ by mechanical or liquid exfoliation. The powdered form is suitable for liquid chemical exfoliation to prepare nanosheets and nanoparticles down to few-layer films.

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.
