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 S^2- atoms while Ag⁺ is bonded in a 2-coordinate geometry to six S^2- atoms. S^2- sites are inequivalent in the structure with each of one set of S^2- ions is bonded in a 3-coordinate geometry to three equivalent Ta⁵⁺ and two equivalent Ag⁺ atoms while each of the other set S^2- 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.
