High quality, high purity AgTaS3 powder

Suitable to process nano-plates into few-layer films

Technical Data | MSDS | Literature and Reviews  | Related Products

2D layered silver tantalum sulfide (AgTaS3) belongs to the family of ternary metal sulfides which are promising alternatives to noble metals for its excellent redox reversibility, high electronic conductivity and capacitance. Binary metal sulfides can be used as electrode materials for lithium-ion batteries (LIBs), supercapacitors (SC), and solar cells applications.

Atomically thin AgTaS3 layers can be synthesized through a facile probe sonication exfoliation of either bulk crystals or powder.

Structure of Silver Tantalum Sulfide Powder

AgTaS3 crystallizes in the orthorhombic Cmcm space group in three dimensional structure. Ta5+ is bonded in a 8-coordinate geometry to eight S2- atoms while Ag+ is bonded in a 2-coordinate geometry to six S2- atoms. S2- sites are inequivalent in the structure with each of one set of S2- ions is bonded in a 3-coordinate geometry to three equivalent Ta5+ and two equivalent Ag+ atoms while each of the other set S2- ions is bonded to two equivalent Ta5+ and two equivalent Ag+ atoms to form corner-sharing [STa2Ag2] tetrahedra.

The layer is composed of Ta-centred bicapped trigonal prisms stacked on top of each other by sharing triangular faces with each layers are held together through van der Waals interactions.  Ag+ions reside in the distorted octahedral sites between the 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.
