Silver Indium Phosphorus Selenide (AgInP2Se6) Powder

High purity AgInP2Se6 powder

Excellent for applications in photoelectronic devices

Layered silver indium phosphorus selenide (AgInP₂Se₆) is another family member of hexachalcogenohypodiphosphates family which has a chemical formula of ABP2X6 (A = Cu or Ag, B = In or Bi, and X = S or Se).

Bulk AgInP₂Se₆ crystallizes in the trigonal P-31c space group and its monolayer adopts the centrosymmetric structure, with six equivalent bonds and no shift of metal atoms.

Atomically thin AgInP₂Se₆ layers can be synthesized through a facile probe sonication exfoliation of either bulk crystals or powder.

Silver indium phosphorus selenide powder

Structure of Silver Indium Phosphorus Selenide Powder

The crystal structure of AgInP₂Se₆ is very similar to the that of AgInP₂S₆ and it crystallizes in the trigonal P-31c space group. The structure is two-dimensional and consists of two AgIn(PSe₃)₂ sheets oriented in the (0, 0, 1) direction. Both metal Ag and In atoms are coordinated with six Se atoms and P atoms are tetrahedral coordinated to form a binuclear [P₂Se₆] ^4-cluster which are located in the centre of hexagon composed by alternative three Ag atoms and three In atoms.

AgInP2Se6 monolayer tetrahedral structure

In the bulk and multilayer samples, the neighbouring layers are coupled by van der Waals interactions. The selenium atoms form a hexagonal close packed structure arrangement with the layer sequence ABAB running along c-axis.

Applications of Silver Indium Phosphorus Powder

Monolayer AgInP₂Se₆ is extremely stable semiconductor and its bandgap and light absorption is adjustable by applying strains. Uniaxial and biaxial strains of 0.90 - 1.10 can realize the transition between indirect band gap and direct band gap and the phenomenon of optical red shift. Applying tensile strain will cause the dielectric function spectrum to respond in a lower energy direction. The tunability of the such optical and electrical properties makes AgInP₂Se₆ a great candidate for application in photoelectronic devices.

AgInP₂Se₆ also shows a good photochemical hydrogen evolution reaction (HER) activity.

Synthesis

Obtained via the CVT method, AgInP₂Se₆powder with purities of over 99.995% have been achieved.

Usage

AgInP₂Se₆ powder is suitable for liquid chemical exfoliation to process AgInP₂Se₆ quantum dot solutions and nano-plates down to few-layer films. High-quality, high-purity AgInP₂S₆ powder is also used for CV deposition of ultra-thin single or 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.
