High purity AgInP2S6 powder

Used to process quantum dot solutions and nano-plates into few-layer films

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

Silver indium phosphorus sulfide (AgInP2S6) belongs to the hexachalcogenohypodiphosphates family. AgInP2S6 has a layered structure like most of the other layered materials, i.e. graphite.

AgInP2S6 a typical Transition metal thio/selenophosphates (TPS) with a rhombohedral structure that contains a sulfur framework with the octahedral voids filled by Ag, In, and P–P triangular patterns. 

Atomically thin AgInP2S6 layers can be synthesized through a facile probe sonication exfoliation of either bulk crystals or powder.

Structure of Silver Indium Phosphorus Disulfide Powder

Bulk AgInP2S6 crystallizes in rhombohedral structure and it is non-centrosymmetric with two non-equivalent packet layers in the unit cell. Both metal Ag and In atoms are coordinated with six S atoms and P atoms are tetrahedral coordinated to form a binuclear [P2S64- cluster which are located in the centre of hexagon composed by alternative three Ag atoms and three In atoms. The metal (Ag and In) layers are sandwiched by two layers of S atoms, while the [P2S64- pairs act as stanchions inside the layer. 

unit cell AgInP2S6

In the bulk and multilayer samples, the neighbouring layers are coupled by van der Waals interactions. The [P2S6] dumbbell pairs and Ag atoms stack alternately in the nearby two layers, leading to the AB stacking order of the adjacent layers.

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.
