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, FePS3 is a layer structured antiferromagnetic semiconductor and can be exfoliated into few-layer 2D nanosheets. It is commonly referred to as 'magnetic graphene'.

Iron Phosphorus Trisulfide (FePS3) Powder & Crystal

Powder & Crystal

Available in Powder & Crystal forms

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.

Bulk single iron phosphorus trisulfide crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation. Single iron phosphorus trisulfide crystals, or films produced from such crystals, are suitable for study using atomic force microscopy or transmission electron microscopy.

Few-layer FePS3 nanosheets and nanoparticles can also obtained from iron phosphorus trisulfide powder by liquid-exfoliation.

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 C2h. 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.

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.
