Low price, high purity 2D iron phosphorus triselenide powder and crystal

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

Technical Data | MSDS | Structure | Literature and Reviews | Related Products | Resources and Support

Iron phosphorus triselenide (FePSe3) belongs to a layered MPX3 (M = Mn, Fe, Ni, Zn and X = S, Se) family. FePSe3, with a layered structure like graphite, is a low bandgap ternary magnetic semiconductor with p-type characteristics as grown single crystals. Like FePS3, FePSe3 has also been predicted to have Ising-type antiferromagnetic ordering from its bulk form to the ultrathin nanosheets.

Iron Phosphorus Triselenide (FePSe3) Powder & Crystal

Powder & Crystal

Available in Powder & Crystal forms

Antiferromagnetic semiconductor FePSe3 shows superconductivity along with the structural transition and vanishing of magnetic moment with a starting Tc ~2.5 K at 9.0 GPa and the maximum Tc ~5.5 K around 30 GPa. 

Having a rhombohedral crystal system with space group R3̅ , FePSe3 undergoes isostructural or quasi-isostructural phase transitions under applied pressure at ~8 GPa 

We supply low price iron phosphorus triselenide in several different forms for a range of applications.

*Typical representative size, areas/dimensions may vary

Bulk single iron phosphorus triselenide 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 triselenide crystal or films produced from such crystals are suitable for study using atomic force microscopy or transmission electron microscopy.

Few-layer FePSe3 nanosheets and nanoparticles can also obtained from iron phosphorus triselenide powder by liquid-exfoliation.

Structure of Iron Phosphorus Triselenide

Iron phosphorus triselenide (FePSe3) belongs to a layered MPX3 (M = Mn, Fe, Ni, Zn and X = S, Se) family, having a rhombohedral crystal iron phosphorus triselenide system and contains three layers of FePSe3 per unit cell. 

In the FePSecrystal, the P atom is coordinated to three S atoms and one P atom to form a [P2Se6]4- unit. The [P2Se6]4- unit is connected with six Fe atoms, which are arranged in a honeycomb plane structure. However, unlike FePS3 where the atomic layers of the sulfides stack in the C2/m space group, selenides stack in R3̅. 

Raman spectrum of bulk FePSe3 shows intense peaks at 215 and 168 cm-1 that are assigned to the stretching vibration of P−Se bond in a [P2Se6]4- cluster.

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.
