Manganese phosphorus triselenide (MnPSe₃) is a layered antiferromagnetic (AFM) Heisenberg-type semiconductor with Néel temperature at 74 K.

Monolayer manganese phosphorus triselenide (MnPSe₃) is an intrinsic semiconductor with antiferromagnetic (AFM) ordering at its ground state. Each Mn²⁺ ion is antiferromagnetically coupled to its three neighboring Mn²⁺ ions, forming an AFM ordering. The spin density is mainly localised at two Mn²⁺ ions with the opposite spin magnetic moments, while P and Se atoms have the negligible magnetic moments.

It shows that AFM state is more stable than the ferromagnetic (FM) state by about 40 meV per unit cell for 2D MnPSe₃ and the bulk AFM characteristic can be well preserved in its monolayer structure. However, both electron and hole doping or biaxial tensile strain about 13% can induce its transition from antiferromagnetic semiconductor to ferromagnetic half-metal.

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

Structure of Manganese Phosphorus Triselenide

In its bulk form, MnPSe₃ crystalises in a rhombohedral FeCl₃ structure. Arranged in a honeycomb hexagonal form, each Mn atom is coordinated to and sandwiched by two layers of S atoms, three in each layer. Those S atoms form triagonal pyramids with two P-P atoms at each end of a dumbbell structure. The dumbbell is often referred to as a [P₂Se₆]⁴^- cluster.

Properties of Manganese Phosphorus Triselenide

After exfoliation of manganese phosphorus triselenide crystal or powder, MnPSe₃ typically has the following properties:

Rhombohedral (space group: R3)
Transition metal phosphorus trichalcogenides (MPX₃)
Antiferromagnetic (AFM) Heisenberg-type semiconductor with Néel temperature at 74K.
AFM state is more stable than the ferromagnetic (FM) state
AFM characteristic can be well preserved in its monolayer structure
Transition from antiferromagnetic semiconductor to ferromagnetic half-metal by both electron and hole doping or biaxial tensile strain

Applications of Manganese Phosphorus Triselenide

Manganese phosphorus triselenide (MnPSe₃) single crystals can be used to prepare monolayer and few-layer MnPSe₃ by mechanical or liquid exfoliation. Manganese phosphorus triselenide powder is suitable for liquid chemical exfoliation to prepare MnPSe₃ nanosheets and nanoparticles down to few-layer films.

Manganese phosphorus triselenide (MnPSe₃) has a great potential in spintronics with its particular advantages in solar energy conversion and storage applications and novel spin-valley coupling physics.

Manganese phosphorus triselenide ultrathin films have strong absorption in the visible-light spectrum, photocatalytic water splitting into hydrogen and oxygen simultaneously, broad applicability (pH = 0–7), high carrier mobility and availability from nature abundant elements, MnPSe₃ nanosheets has great potentials as photocatalysts for water splitting.

What is spintronics? Spintronics is the study of the intrinsic spin of the electron and its associated magnetic moment. Spintronics measurement does not relies on electrons' charge, but on another of their fundamental quantum-mechanical properties, spin.

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.
