High purity AgInP2Se6 powder

Excellent for applications in photoelectronic devices

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

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.

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 [P2Se64- 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.

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.
